摘要
文章以盐城金鹰内港湖B1地块项目基坑工程为背景,结合场地工程地质条件、地下室结构布置特点、工期计划及一、二期工程支护结构特点,对一、二期分界处支护技术进行多方案比选,介绍了高压旋喷加劲桩支护方案的优点,并结合工程实施及监测情况,验证其合理性,取得了较好的经济效益。
Based on the project of Yancheng Golden Eagle Neiganghu B1 plot excavations engineering,Combined with the engineering geological conditions of the site,structure of basement characteristics,time schedule, retaining and protection structure characteristics of the first and second phase of the project, scheme comparison retaining and protection for excavations located at the boundaries of first and second phase of construction. It introduced the advantage of the high pressure jet grouting reinforced cement pile scheme,And combining with the implementation of the project and monitoring results,the rationality were validated experimentally,obtained better economic benefits.
