摘要
花岗岩球状风化体(俗称孤石)发育特征对桩基础施工工期、成本及质量有较大影响。本文选取一个孤石集中发育的典型工程项目,从场地各风化层孤石数量、孤石揭露厚度及孤石分布层数三个方面进行统计并分析其分布规律,同时总结了孤石与基岩在桩基础施工过程中判别及利用的经验,希望为类似工程提供借鉴。
The development features of weathered spheroidal granite(commonly known as solitary stone)has a great influence on time limit of construction,cost and quality of pile foundation.This article selects a typical engineering project of concentrated developed solitary stone,analyzes the distribution law from three aspects such as the solitary stone number of different weathered beds in the granite region,uncovered thickness and the solitary stone number of layers.At the same time,the experience of distinguishing and utilizing bedrock and solitary stone in the pile foundation construction is summarized.It is hoped to provide references for similar projects.
