基坑圍護設計中的問題及對策
　　摘 要：本文針對當前基坑工程因設計問題而造成工程事故或浪費的現狀問題，分析了產生問題的原因，指出設計方法存在的缺陷，并針對問題提出了對策。
　　隨著高層建筑的增多和城市用地的日益減少，基坑工程設計和施工涉及的地質條件、巖土性質、場地環境、工程要求、地下水動態、施工順序和方法 等許多問題越趨復雜，使基坑的開挖和圍護結構的設計成為一個具有挑戰性的巖土工程熱門難題。而基坑工程的迅猛涌現與相應設計理論和方法的滯后，給基坑圍結 構護設計工作帶來了極大的因難，也使基坑工程的設計與工程實際狀況存在較大偏差，其結果是造成工程事故或浪費。
　　1、當前基坑圍護設計現狀
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.
1, the current status of Foundation Pit Design
