临海淤泥地质条件基坑开挖支护技术

Excavation and support technology of foundation pit in coastal silt geological conditions

为解决临海淤泥地质条件基坑开挖支护的施工风险和施工难度问题,结合青岛市市民健康中心基坑工程的实际情况,就临海淤泥地质条件基坑开挖支护各项施工试验及施工方案的确定展开讨论.最终经过反复试验和理论分析,总结出一种临海淤泥地质条件下的基坑开挖支护技术.对以强夯置换墩作为基坑支护及淤泥开挖的类似工程的设计和施工提供了理论依据和施工经验.

To solve the risk and construction difficulty for the excavation of foundation pit under the condition of coastal silt geology,we had a discussion on the respective tests and methods for the excavation and support under coastal silt geology,integrated with the actual situation at the foundation pit for the health center of citizens in Qingdao.At last,we got a technology after the repeated tests and theoretical analysis.The dynamic replacement is used as the excavation and support for the foundation pit,as provides the theoretical accordance and construction experience for the design and construction of similar projects.
