| Abstract: | From the actual situation of the deep foundation pit City, the paper analyzed the engineering properties of the soil, of Wal-market Commercial Square in Yuxi the stratum structure, the condition for its basement design and the surroundings around the foundation pit. The choice of supporting the deep excavation by using deep core mixing pile and pre-stressed anchor bolt in soil-nailed was made after a careful comparison among plans of row-pile support, soil-nailed wall support and compound soil-nailed wall. Design and construction process of compound soil nailing were introduced in detail. The practical application can ensure the safety of the buildings around foundation pit. |
