地下综合管廊施工中的土力学问题研究
摘要
地下综合管廊建设是解决城市地下空间开发的有效途径之一。在其施工过程中，土力学问题是不可避免的。本文以某综合管廊工程为背景，探讨了其施工过程中的土力学问题。首先，对工程场地的地质条件进行了勘查和分析，确定了施工期间的土体力学性质；其次，基于现场施工资料和数值模拟，针对施工过程中土体的变形及支撑结构的破坏等问题进行了深入分析和研究；最后，通过对相关实验结果的验证和整理，提出了一系列应对土力学问题的有效措施和建议。研究结果表明，能够采取合适的支护措施和施工方案，有效避免土体变形和结构破坏。从而为地下综合管廊施工提供了基础性的参考。
关键词：地下综合管廊、土力学、支护结构。
Abstract
Underground comprehensive pipe gallery construction is an effective means of developing urban underground space. However, geotechnical problems cannot be avoided during the construction process. This paper focuses on a certain comprehensive pipe gallery project and explores the geotechnical problems during its construction process. Firstly, the geological conditions of the construction site were investigated and analyzed to determine the soil mechanics properties during construction. Secondly, based on on-site construction data and numerical simulations, in-depth analysis and research were conducted on the deformation of the soil and the damage to the support structure during construction. Finally, a series of effective measures and suggestions to deal with geotechnical problems were proposed through validation and collation of relevant experimental results. The research results show that appropriate support measures and construction plans can be adopted to effectively avoid soil deformation and structural damage, providing a fundamental reference for the construction of the underground comprehensive pipe gallery.
Keywords: Underground comprehensive pipe gallery, geotechnical, support structure.
