摘要
介绍在8度沿海震区群桩基础设计中碰到的技术难点和解决方法。基础设计需要综合考虑安全可靠、经济合理和技术先进,并顾及周围的施工环境和施工难度等因素。该工程采用钻孔灌注桩基础+承台+连梁的设计方案,借助有限元软件进行建模和计算地震作用力、基础连梁梁端弯矩及其应力和地脚螺栓力等。全面优化设计,可为今后同类工程的基础设计提供有价值的参考。
The crux and its solution encountered in the design of group piping foundation in the coast line seismic area of 8^th Richter scale is introduced. The design shall consider the factors of safety and reliability, rational in economy and advance in technology, taking into account the functioning circumstance and difficulties as well. The project applies an engineering scheme of drilling-hole driven cast-in-place pipes ＋ piping platform ＋ linking beams. The calculation of seismic actions, the bending moment of foundation linking beams and footing bolts is done basing on modeling with finite-element soft-ware. The deign subjects to optimization and is worth as the reference for the similar engineering afterward.
