故宫西南区域岩土工程勘察及基坑支护方案研究

Study on geotechnical engineering investigation and foundation pit supporting scheme of the southwest area of the Forbidden City

通过对故宫西南区域现场勘察和室内试验,分析建设场地地基土的物理力学性质以及天然地基承载力,研究基坑支护体系及施工方案。基坑监测结果表明,该施工工艺及基坑支护方案可以保证基坑边坡稳定及施工安全,为文物保护区内相关基坑支护方案的制定提供了参考。

This article analyzes the physical and mechanical properties of the foundation soil and the natural bearing capacity of the construction site through on-site investigation and indoor tests in the southwest area of the Forbidden City,and studies the scheme of the foundation pit support system.The actual monitoring results indicate that the construction process and foundation pit support plan can ensure the stability and construction safety of the foundation pit slope,providing a reference for the deep foundation pit support plan in the cultural relics protection area.
