混凝土灌注桩及土钉墙在某基坑支护中的应用

摘要

介绍了基坑支护工程需要满足的施工要求，结合工程实例，通过分析工程的地质条件，阐述了混凝土灌注桩及土钉墙在基坑支护工程中的施工技术，并对基坑支护结构进行了变形观测，表明了该施工技术方案的合理性。%This paper introduced the construction requirements of foundation pit support engineering to meet,combining with the engineering example,through the analysis on engineering geological conditions,elaborated the construction technology of concrete bored pile and soil nailing wall in foundation pit support,and made deformation observation of foundation pit support structure,verified the rationality of construction technology program.
