文章“之一”介绍了条形地下墙深基坑周围地层移动的机理和相关因素以及地下墙深基坑施工技术要点,现对基坑周围地层移动的预测进行论述。本文对实际工程中常用的经验公式预测法、半理论解析法和数值模拟法作了详细分析,阐明了在基坑周围地层移动预测中的一个指导思想——目前阶段在处理复杂土工技术问题中,要采取理论导向、测试定量和经验判断相结合的方法,以求可靠、实用和简易的技术效果,对地下墙深基坑施工具有实际指导意义。
The paper “One” introduces the mechanism and related factors of formation movement around the deep foundation pit of the strip underground wall and the key points of the construction technology of the deep foundation pit. The prediction of the formation movement around the foundation pit is discussed. In this paper, the empirical formula prediction method, semi-theoretical analysis method and numerical simulation method commonly used in practical engineering are analyzed in detail, and a guiding principle in the prediction of formation movement around the foundation pit is expounded. At present, in the process of dealing with complex geotechnical problems , It is necessary to adopt a combination of theoretical guidance, quantitative testing and empirical judgment in order to achieve reliable, practical and simple technical results, which have practical guiding significance for deep foundation pit construction of underground walls.
