深港西部通道侧接线隧道工程地道高性能混凝土技术研究与应用

Study on underground high performance concrete and its application in Shenzhen side-connection item of Shenzhen-Hong Kong west channel project

深港西部通道侧接线工程处于深圳湾填海区段,是深圳市的重点工程。在探讨了隧道工程的环境特征及作用等级,结构腐蚀原因;提出了适应地道结构近海腐蚀环境的高性能混凝土配制原则、性能指标以及技术要求。根据研究结果,对深港西部通道侧接线隧道工程中的实践应用的高性能混凝土进行了验证和评估。

Shenzhen side-connection item of Shenzhen-Hong Kong west channel project is an important project of Shenzhen,which locates at reclamation land in Shenzhen Bay.The geological environment and its influence to underground high performance concrete structure is analyzed and estimated.And,the technical target and technical requirement of high performance concrete is shown.After all, the material properties and mixing proportion of high performance concrete is evaluated, which satisfies the project requirement.
