深大竖井开挖及逆作法施工技术研究

Research on excavation and reverse construction technology for deep and large vertical shafts

摘要

逆作法是一种超常规的施工方法，一般是在深基础、地质复杂、地下水位高等特殊情况下采用，地下结构采用逆作法施工，相比传统的施工方法可降低造价、缩短工期，减少周边环境的影响，施工安全又能得保证，是施工高层结构地下室或地下结构的有效方法。但地下结构的理论分析起步较晚，特别是施工方面理论还不是很完善，因此对施工过程的深入细致的研究是十分必要的。

Abstract

Reverse construction method is an unconventional construction method, generally used in special situations such as deep foundations, complex geology, and high groundwater levels. Underground structures are constructed using reverse construction method, which can reduce costs, shorten construction periods, reduce the impact on the surrounding environment, and ensure construction safety. It is an effective method for constructing high-rise basement or underground structures. However, the theoretical analysis of underground structures started relatively late, especially in terms of construction theory, which is not yet very complete. Therefore, it is necessary to conduct in-depth and detailed research on the construction process.
