The Research On Applicability And Economical Efficiency Of The Self-Balance Retaining Wall

Along with the rapid economic development, our country needs to carry out large-scale construction of basic infrastructure facilities,urban construction in order to satisfy the growing economic and social development. And many construction projects are directly related to the excavation of the slope or supports. Due to the site conditions and the complex geological conditions, so that the slope stability is affected by many factors, Therefore slope of supporting forms should also satisfy the increasingly severe situation of the slope.This paper describes some of the existing forms about support and give a brief description of the existing forms about support advantages and disadvantages as well as pointing out that the existing forms of support has some difficulties to meet the increasingly serious situation of slope. Since the self-balance retaining wall is a new support structure which is developed from the original form of support. It makes use of gravity which is transmitted from the upper structure of the the slope , it keeps the thrust blance and make the entire wall and the slope in balance.Since this paper regarding balance wall as research object and systematically analyzed the principle the balance between retaining wall, then come to a conclusion that: balance wall clever using the weight of the upper structure to balance the slope, avoiding the lateral support of the traditional structure, so that structural system is good relative independence. Such characteristics make balance retaining wall anchor for the poor conditions of the building, able to adapt to the current conditions of complex slope venue harsh environment. Since the self-balance retaining wall combined the merit of the gravity retaining wall and sliding pile, so it is more adaptive. It not only can reduce the bending and lower rate of reinforcement, anchoring depth and construction costs, but also can shorten the construction period.and support higher slope. On this basis, a self-retaining wall reasonable balance between the applications of several functions, types of venues. To study the economic advantages of the self-balancing wall of using a set of assumptions venues, three different slope support program were compared. Quantitative verification of the self-balancing wall structure more rational and economic use, came to its costs to save 10~40% than other support program. The conclusions will provide reference for engineering design selection program structure.Finally, aimed at the actual slope engineering of a district of Chongqing Municipality, applied the balance of retaining wall design, the analysis showed: a reasonable balance between retaining wall structures, slope stability, the bracing effect, the economic results are better than other types of retaining structure. But the research about balance wall, as a new retaining structure, has barely begun. There is still plenty of researching work need to do. It will become the emphasis in the next step research.
