A Research of Life Cycle Integrated Management Pattern of Construction Project

Development Management (DM) in decision phase, Project Management on behalf of the owner (OPM) in implementation phase and Facility Management (FM) in operation phase are three isolated management tools during traditional life cycle management of construction project. As a result, a lot of potential disadvantages are aroused. In recent years, many research organizations try to reform the traditional method using different integration means. This paper tries to explore into integration of DM, OPM and FM to overcome the malpractice of traditional life cycle management of construction project. The research focuses on three aspects: 1.putting forward the concept of Life Cycle Integrated Management (LCIM), based on management integration theory; 2. Raising a new idea to owner's (operator's) management organization design, which emphasizes on the balance of life cycle objectives; 3. Analyzing an information module, level and method of system integration of Life Cycle Integrated Management Information System.

Relationship changes between lowlander and hill tribes in Xishuangbanna,P.R. China

Xishuangbanna, which is well known for its ethnic diversity, is located in the upper reaches of the Mekong River. Dai lowlanders make up one third of the total population, 13 other indigenous highland groups make up another third and the balance are Han Chinese. The research on which this paper is based was conducted in three villages, Dai, Hani and Jinuo communities and designed to explore the changing relationships between lowlanders and highlanders. It was found that over the past five decades two critical events triggered profound changes. One was liberation by the Chinese Communist Party in 1950, and the other the land and economic reform policies introduced at the beginning of the 1980s.

Cutting Wheel Structure Selection of EPB TBM and Its Adaptability Evaluation in Large Particle Size Gravel Strata

Large particle size gravel strata layer is very difficult for TBM construction which brings about a series of problems for EPB TBM advancing in Beijing Metro. Cutting wheel is an important component of EPB TBM and cutting wheel with reasonable structure is essential for EPB TBM to advance steadily and effectively in large particle size gravel strata. In-situ EPB TBM advancing tests are carried out in large two adjacent shield interval where the strata conditions make it possible to find out the most efficient cutting wheel structure by monitoring key parameters through Real-time Information Management System. Based on the analysis and comparison of advancing efficiency, strata adaptability of key parameters and tools wearing, the following conclusions can be obtained: 1) Spoke cutting wheel has better strata adaptability and higher efficiency than panel cutting wheel as well as more advantages in controlling tools wearing. 2) open ratio ranging from 55% to 65% is the reasonable for cutting wheel. 3) Advancing speed and earth pressure are very important for EPB TBM construction. Compared with panel cutting wheel, spoke cutting wheel can obtained higher advancing speed and more stable earth pressure in tests. However the change of earth pressure should also be paid attention when EPB TBM advancing in fast speed. The advancing speed should be controlled in the range of 20 to 60 mm/min.
