Research on the System and Models of Society-Economy-Environment Appraisal for Construction Project

The society-economy-environment appraisal for construction project can help our government to control macro-economy, make correlation policy and formulate laws and draw up city plan.It has great influence on the sustainable development of our society and it is the demand of the law for the environment evaluation in China.This paper introduced the basic structure of society-economy-environment appraisal system for construction project and the thought of elements transaction.Using the method of AHP, the model of project analyzing and optimizing selection is designed.For the more, the methods of the optimizing models on the selected schemes are put forward.Finally, the integrative analysis has been made on the system design and appliance of this appraisal system.     

Design of Reef- blasting Project and Analysis of Regulation Effect for Fuling to Tongluo Canyon Reach in Three Gorges Reservoir Region

After the completion of the Three Gorges project,the navigation conditions of the reservoir region will be improved evidently,which has laid the foundation for straight run of the 10,000-ton-class fleet to Chongqing Port,and is the promotion of the development of shipping in Yangtze River.But according to the standard of the 10,000-ton-class fleet,there are still some reaches of the reservoir region can not meet the requirements of the waterway on smooth and safe navigation.Therefore,some regulation measures should be adopted to eliminate these obstructions.It is one of the important parts in the reservoir region waterway regulation work for the Fuling to Tongluo canyon reach blasting project.30 reef obstacle blocks of 14 reaches in this project were removed by blasting.Based on the analysis of obstruct features of various rocks,according to the standard of the 10,000-ton-class fleet,the design parameters and blasting regulation program were put forward,and the regulation effect is analyzed and forecasted.     

Analysis of Social Appraisal Index System in Public Project

The social evaluation theories of public project still have not been standardization today, and have effects on the process of the construction to city. One of the main reasons lays in that the index system, about the social evaluation theories of public project, connects with many fields, has many non-economic index and difficult in measuring the every index. This article is to mark off the main factors involved in social evaluation effectually, to set up index system of social evaluation practically, and to settle firm ground for methodology and theory of public project.     

Prediction of the Economic Development for the Circumjacent Reservoir Region of the Longtan Hydropower Project Using Grey Quantitative Analog

In order to overcome some technical difficulties,we adopt ingenously the grey models combined with the quantitative analog method,and select the Dan Jiangkou Project which has accumulated practical operation data for a long time as the analog project to predict the economic influence for the circumjacent reservoir region of the Longtan hydropower project.On the basis of analog we have built various industrial economic grey models,and compare them with the corresponding predictions for the unconstructed reservoir case.The predictions of the former are greatly larger than the later ones.and hence provides a certain scientific basis for the central leaders to make a decision for constructing the huge hydropower project ultimateiy.     

Energy Efficiency Analysis of Heating System in the Birdhouse

In this paper the problem of energy consumption and environment in the birdhouse is introduced and the reconstructive measures aiming at energy savings are recommended. The measures include the limitation of temperature region, reconstruction of the building envelop and using the sunny board at the south side of the birdhouse roof. Finally, the energy efficiency of the reconstructive project is estimated.     

Analysis of Project Audit''s Function and Civil Action

Audit takes a unique status and has obvious function in financial surveillance system.The Audit is used to superintend the factuality,validity and virtue of fiscal and financial income and expenses.In the renewed China Audit law the functions and status of official audit have been intensified,and the qualification and status of Audit department as executing office is confirmed.This paper analyzed the official construction project audit's function and legal status.     

Discussion about the Agent- Construction System of Governmental Project in China

The agent - construction system, as a new public project management mode, has been practiced in some cities and attracted attention from the society. This paper firstly studies the features and operation modes of agent - construction system, and discusses the agent - construction system from the viewpoints of promoting competition, nourishing agent -construction enterprises, setting up a supervisory and encouraging mechanism, and its connection with the governmental project procurement system etc.     

Control and Analysis on Environmental Object of Construction Project

With social development, the environment has become one of the major topics in human life. Although the construction project may improve economy and environment, it also may exert negative impact on environment. Cost, schedule and quality are three important objectives of construction project and on the objective of environment have not been focused. The author of this paper reiterated the importance of environmental control for the construction project and key areas to be focused on during the whole process of construction project.     

Approach to Effective Control on the Project Investment

In this paper, in allusion to the three kinds of serious overvaluation (the budgetary estimate of project construction exceeds the rough estimate, the budget exceeds the budgetary estimate and the final accounts exceed the budget) causing uncontrollable project investment often appeared in domestic project construction,the main causes for that are analyzed. That is, the frequent project change and the malpractice of the cost managing system. In this paper, according to some real projects,the kinds and causes of project change are clarified and the malpractice of the cost managing system is analyzed. The effective approaches of reducing the project change, especially the united surveying and improving the cost managing system in order to make the effective control of the project investment are realized.     

Nonlinear FEM Analysis of RC Staggered Joint by Using APDL Language

In order to settle some problems involved in applying ANSYS into nonlinear Finite Element Analysis of RC structure,this paper discusses the nonlinear FEM method for staggered joint,incorporating its experimental result.The main solved problems are as follows:(1) The fundamental process of nonlinear FEM analysis;(2) How to model the behaviors of reinforcement and concrete respectively;(3) How to model the bond-slip relationship between reinforcement and concrete.
