Technology Research For Excavation Engineering Construction Of Low Environmental Hazards

Long-term since, people are studying the deep foundation pit engineering with the traditional soil mechanics theory, such as the analysis of active earth pressure, passive earth pressure etc, which are from the natural undisturbed soil for the static objects. But because of the soil excavation, makes the soil stress change, then affects their strength. In other words, the theoretical analysis with static dynamic practical problems, is far from enough. Thus causing all kinds of environmental hazards that is worthy of our attention. For example the soil instability and destruction, structure changes, and the influence of the surroundings. Therefore, how to analyze the construction process of the surrounding soils and change the influence of construction engineering, and reduce to the periphery environment construction of foundation pit the influence of paper, is the main problem to solve.This paper firstly introduces the construction of deep foundation pit engineering, the influence of the surroundings, and produce a series of problems, and put forward the concept of low environmental hazards, then for deep foundation pit excavation construction pile driving construction, construction of underground continuous wall, and main construction method, the low environmental hazards analysis, theoretically understanding the causes of environmental hazards.Again, take necessary for reasons of prevention and protection measures. Prevent mainly through monitoring means. Monitoring construction process the harmful factors and theory of monitoring alert value, compared to determine whether displacement or stress state more than allowed scope, judge whether security, whether for construction surrounding environment adversely.According to the analysis of the low environmental hazards, taking protective measures is very necessary. There are many methods to control the low environmental hazards, this article mainly introduced the information construction, top down construction method etc effect obvious way and then through the construction of foundation excavation Wuhan Business Moore town of computer simulation verified the feasibility of low environmental hazards.
