深基坑支护内力稳定性及降水引起的沉降分析
土木工程专业
[摘要]随着城市建设的迅速发展,高层和超高层建筑的不断涌现,地下空间的开发势在必然。基坑工程往深、大方面发展,深基坑的支护和降水是保证基坑稳定的最主要的工作内容,特别是当地下水埋置很浅的时候,基坑降水是必须要进行的,降水工程是基坑工程中重要组成部分。同时深基坑工程中,由于周边建筑密集、管线分布杂乱、场地狭小等,给深基坑工程带来很大的难度及复杂性。原有的一部分经典理论和支护方法已满足不了实际的需要,经典的朗肯土压力理论和库伦土压力理论都是假设土体处于极限平衡状态下推导出来的,而实际的支护结构很难达到极限状态那么大的位移。土体处于非极限状态下的土压力及其分布形状,不仅与土质有关,而且在很大程度上取决于支护结构的变形情况。
在此通过对基坑开挖支护等相关内容的学习现在我主要介绍一下深基坑支护结构在考虑位移影响的计算方法的研究和基坑降水引起的建筑物沉降分析。

Abstract: With the rapid development of urban construction, the growing emergence of tall and super-tall buildings, underground space development of hindering. To deep foundation pit engineering, big developments, deep foundation pit support and precipitation is the main work content, guarantee the stability of foundation pit, especially local embedded water is very shallow, foundation pit precipitation is has to be, is an important part in foundation pit dewatering engineering. Deep foundation pit engineering in at the same time, due to the surrounding buildings dense, narrow pipeline distribution clutter, site, etc., to a lot of difficulty plexity of deep foundation pit engineering. The original part of the classical theory and the supporting method already can't satisfy the actual need, the classical Rankine's earth pressure theory and coulomb's earth pressure theory under the soil in limit equilibrium state are derived, and the ac
