摘要

通过某电厂桩基处理工程实例，介绍了打桩引起的预制桩偏位及开挖问题。在不加外荷载情况下，采用塑料排水板方法消散打桩引起的超静孔隙水压力的处理措施，解决了高孔隙水压力下主厂房的开挖问题。分析了塑料排水板消散孔隙水压力的影响因素。观测结果及工程实践表明，塑料排水板处理桩基工程快速经济，可不需加载，但处理效果与水平排水系统有关。

Abstract

The deflection of precast piles and excavation problems induced by pile driving are introduced through an engineering case of pile foundation treatment of a power plant. The treatment and effectiveness by use of prefabricated drains method to dissipate the excess pore pressure by pile driving are also introduced under the condition without external loads. The excavation problems of the main power house under high pore pressure is solved; and factors related with prefabricated drains to dissipate pore pressure are analyzed. The observed results and engineering practice show that the pile foundation treatment by use of prefabricated drains is fast and economic; and it employs no external loads

however

the treatment effectiveness relates with the horizontal drainage system.
