摘要
韩庄锚泊区墩台基础设计为灌注桩,由于全线分布的含姜石粉质粘土埋深浅,导致施工钢平台入土深处不足。施工平台采用“板凳桩”结构型式,通过Midas建立有限元模型,计算其在施工荷载作用下的平台受力性能,结果表明平台的各类构件受力均在容许范围内,平台的刚度、强度及稳定性均满足钻孔时的要求。
Cast-in-place piles serve as platform foundation in the design of Hanzhuang anchorage area.Due to shallow buried-depth of silty clay containing ginger like stones that covers the whole area,the construction steel platform cannot be driven to the design depth,so bench-pile rig is adopted here.A finite element model is built by Midas to calculate the mechanical performance of the rig under construction load.The results show that the stress on various components are within accepted range,and the stiffness,strength and stability of the rig meet drilling requirements.
