深墩基础即基础底面的埋置深度比一般基础深的墩式基础(或称柱式基础),其埋深可达8～15m。上部土壤比较软弱以及地下有防空洞的部位,在无法采用桩基础的情况下可采用深墩基础。一、深墩基础的设计 1.结构型式深墩基础的结构型式如图1所示,用毛石混凝土浇筑,或用毛石砌筑。基础的底面面积由计算确定,深度视地基土质情况或地下防空洞的深浅而定,下部的大放脚应满足基础刚性角的要求。
The deep pier foundation, which is the pier foundation with deeper foundation foundation than the general foundation (or pillar foundation), has a depth of 8 to 15m. The upper part of the soil is relatively weak and there are air defense holes in the underground. The deep pier foundation can be used when the pile foundation cannot be used. First, the design of deep pier foundation 1. Structural type deep pier foundation structure type shown in Figure 1, with rubble concrete pouring, or rubble masonry. The base area of the foundation is determined by calculation. The depth depends on the ground conditions of the foundation or the depth of the underground air-raid shelter, and the foot of the lower part should meet the requirements of the basic rigidity angle.
