摘要
地基处理是水工建筑物设计最重要的内容之一,为提高深厚软土地基处理设计水平,通过分析珠三角沿海地区水工建筑物地基特点及存在主要问题,总结常用的水泥搅拌桩、预制桩及灌注桩等地基处理方式在适用条件、施工条件及环境影响、施工工期、工程造价、加固效果等方面的差异,并探讨近年来应用相对广泛的刚柔复核桩基的布置、设计原则,结合本地区工程经验,提出了深厚软土上采用刚柔复合桩基设计方案的注意事项。
Foundation treatment is one of the most important contents of hydraulic structure design.In order to improve the design level of deep soft soil foundation treatment,this paper analyzes the characteristics and main problems of the foundation of hydraulic structures in the coastal areas of pearl river delta.This paper summarizes the differences of common foundation treatment methods such as cement mixing pile,precast pile and cast-in-place pile in terms of applicable conditions,construction conditions and environmental impact,construction period,project cost and reinforcement effect.In addition,the layout and design principle of rigid flexible composite pile foundation,which is widely used in recent years,are discussed.Based on the engineering experience in this area,the design scheme of rigid-soften composite piles foundation on deep soft soil is proposed.
