摘要
某国家重点工程项目,需要在海边进行深基坑开挖,最大深度达到32.3m。基坑东侧和北侧淤泥层最厚处接近10m,南侧和西侧主要为基岩,需爆破开挖,地质情况复杂。本监测工程项目通过动态监测,实现动态管理及信息化施工,并验证基坑支护设计方案是安全可行的。
A national key project needs a deep excavation on the seashore with the maximum depth up to 32.3 m. The geological conditions there are very complicated, in the east and north side of the excavation, the sludge is more than 10 m; in south and west side of the excavation, the bedrock needs to be blasted. By dynamically monitoring, the project carries out information-based construction, and it also proves that excavation bracing and retaining solution is safe and flexitle.
