摘要
Abstract
In order to explore the support scheme for deep foundation pits in high pressure water layers adjacent to buildings,the foundation pit of Xinzhu Road Station on Jinan Metro Line 2 was taken as the research object.The feasibility of the drilling and grouting pile+rotary jet grouting pile water stop+internal support support scheme was analyzed using on-site monitoring and mechanical analysis methods.The results show that this scheme can effectively control the deformation and displacement of the retaining structure,and the internal force of the retaining structure is also within a controllable range;When the second steel support is removed during construction,there is a significant change in the displacement and internal force of the retaining structure,and it is necessary to promptly construct the main structures such as the bottom plate and middle plate;According to the on-site monitoring situation,the post construction data changes steadily and the overall safety status is relatively stable,meeting the expected requirements.关键词
