基坑围护设计中的问题及对策
　　摘 要：本文针对当前基坑工程因设计问题而造成工程事故或浪费的现状问题，分析了产生问题的原因，指出设计方法存在的缺陷，并针对问题提出了对策。
　　随着高层建筑的增多和城市用地的日益减少，基坑工程设计和施工涉及的地质条件、岩土性质、场地环境、工程要求、地下水动态、施工顺序和方法 等许多问题越趋复杂，使基坑的开挖和围护结构的设计成为一个具有挑战性的岩土工程热门难题。而基坑工程的迅猛涌现与相应设计理论和方法的滞后，给基坑围结 构护设计工作带来了极大的因难，也使基坑工程的设计与工程实际状况存在较大偏差，其结果是造成工程事故或浪费。
　　1、当前基坑围护设计现状
Foundation Pit Design Problems and Solutions
Abstract: In this paper, because of the current excavation engineering accidents caused by design problems or the status of waste problems, analyze the cause, that the design method of shortcomings, and propose a countermeasure against the problem.
With the increase in high-rise buildings and urban land dwindling, foundation design and construction related to geological conditions, soil properties, and environment, engineering requirements, groundwater, construction sequence and methods, and many other issues become more complex, the base pit excavation and retaining structure design of a popular challenging geotechnical problems. The Foundation's rapid emergence of design theory and methods and the corresponding lag, to the excavation in the design of structural protection brought great difficulties, but also to the design and engineering excavation there is a big deviation of the actual situation, its The result was a work accident or waste.
