摘要
根据饱和黄土高灵敏度的特点,考虑周边特殊环境,本着安全、经济的原则,认真分析了实际工程项目开挖过程中出现的周围土层存在大量水平管路、管线的情况,采用了土钉墙+高灵敏度锚杆、超前锚杆等技术,根据"换撑原理"应用了钢管内撑技术,对深基坑开挖支护进行了研究.结果表明:运用这些技术手段,确保了周边建(构)筑物的安全,取得了很好的经济效益和社会效益.
By considering the high sensitivity of saturated loess and the special surrounding environment,especially the underground pipelines,deep foundation supporting technology was studied.And some techniques such as internal supporting of steel pipes,supporting of soil nail wall and anchor,and supporting of advance anchor were employed.The results show that the proposed techniques ensured the safety of surrounding project and achieved good economic and social benefits.
