A STATIC STRESS ANALYSIS OF THE EFFECT OF STRATIFICATION PLANE OF ROCK MASSES ON SMOOTH BLASTING

The influenfial factors of stratification plane to smooth blasting are studied according to the ti eory of smooth blasting and the anslysis of static stress. The results show that the angle p between the maximum principal plane and the rertical line of stratification plane has some influence on the fracture of rock masses.     

THE ARC-LENGTH METHOD OF SECANT RIGIDITY IN FRAME ANALYSIS

The secant rigidity is used for the are-length method to solve the nonlinear finite elements problems. The advantage of this method is unnecessary of calculating the initial resistance term caused by the incremental step. The computational work is less and the programing is easier as compared with initial are-length method. This method can be widely used to solve nonlinear problems.     

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.     

THE APPLICATION OF SAND-GRAVEL-CUSHION TECHNIOUE IN THE FOUNDATION OF MOUNTAINOUS AREA

This paper presents the application of sand-gravel-cushion technique in thefoundation of mountainous area inhomogeneity and analyges non-uniformity of the foundation inmountainous,It is different from the traditional theory of sand-cushion,This is a new developmentand able to make a full use of the rock debris fill and the combinational soil-rock foundation in the mountainous areas.     

Region Study on Sciences of Human Settlements in China

By review of region study in recent development of history science, geography and Sciences of Human Settlements, this paper points out that material collecting without interrelated analyzing as well as focusing on main question and assumption without enough argumentation are main problems in this field now. The method renovation & combination with related subjects are discussed, this paper concludes that strengthen interdisciplinary study with Geography is a key issue in the future development of region study in Sciences of Human Settlements and possible approach to "technical development' and "humanity concern'.     

Sociological Factors about the Urbanization of Traditional Community --Discussion on Ciqikou Community

The modernization has been the dream that Chinese nation has wished eagerly to realize all the time. In some sense, the modernization of China means urbanization. The reform and opening - up over the past 20 years , built and made the enormous achievement in urbanization of China, have changed the appearance of the city of China greatly. But to numerous traditional historical zones, what kind of urbanization way should on earth be taken, it has been the question long - term in dispute of the planning circles all the time. In this paper, Ciqikou community of Chongqing as an example, doing some discussions from sociology on this question, the author hopes, that for such difficult problem, by this settlement a piece of breach can be found as soon as possible.
