| Abstract: | The densely arranged cut-cast piles were originally designed for the reinforcement of the major foundation pit of Shipaiqiao Station of Guangzhou subway. This present paper have conducted optimization calculations on the design to give a scheme of sparse arrangement of piles spaced at an interval of 2.0 m and then analysed in detail the safty of the sparsely arranged scheme and its effect on the major structure. The calculation results have shown that the new scheme can not only ensure the pits safty but also have a marked economical effect. |
