Abstract
Aiming at the low efficiency of underground diaphragm wall formation in the deep foundation pit enclosure structure of a water resource allocation project in Guangdong,combined with the hydrogeological conditions of the construction site,the surrounding environmental conditions and the current conditions of the construction,it was optimized,and a combination of long and short footing wall(depth of the short wall is 30m,and depth of the long wall is 39m)was proposed,and numerical simulation was carried out by using the finite element analysis software MIDAS/GTS,and the feasibility of the footing wall program was verified by practical testing.From the calculation and analysis of the footing wall under the excavation condition of the pit,the calculation and analysis related to the lining wall under the operation condition,and the practical test,the feasibility of the footing wall program is verified,and experience is provided for the subsequent design and construction of the deep foundation pit enclosure structure.关键词
