建筑基坑侧壁主动土压力计算原则探讨
摘要:随着城市建设对地下空间的利用越来越多、越来越密集，近年来在岩土工程设计工作中常会遇到一些超出规范和标准涵盖范围的工程实况，对于有些问题还存在着国家标准、行业标准以及地方标准各执己见的情况。对基坑侧壁主动土压力计算所涉及到的一些规范和手册的相关条款进行梳理与归纳，对新近常出现但各类规范尚未列出针对性条款的一种工程实况进行原理分析，进而提出针对这种工况的计算原则。目的是将各规范关于基坑侧壁主动土压力计算的条款梳理清晰，对各规范尚未列出的一种工况的计算原则进行建议和补充，使得岩土工程设计工作中的相关问题能够清晰地、有理可据地解决。
Abstract:With the increasing and intensive use of underground space in urban construction, in recent years, some actual projects of geotechnical engineering design beyond the scope of the norms and standards are quite common. However, relevant national standards, industry standards and local standards are different in the specific provisions. The active earth pressure calculation of foundation pit side-wall involved in the relevant provisions of some codes and manuals are sorted out and summarized. The principle analysis of an engineering project case is carried out, which often appears recently but has not yet listed specific provisions in various codes. The calculation principle for this kind of working condition is put forward. The purpose is to sort out the terms of active earth pressure calculation on the side-wall of foundation pit clearly, and provide suggestions and supplements for the calculation principle of a working condition not listed in the specifications, so that the relevant problems in the geotechnical engineering design can be carried out clearly and reasonably.
