苏拉马都跨海大桥工程地质勘察与基础设计

Engineering Geological Investigation and Design of Foundation of Suramadu Sea-Crossing Bridge

采用钻探、物探及室内试验等综合勘察手段,对苏拉马都跨海大桥桥位区域的地形地貌、地质构造、地层岩性进行了描述和分析,为大桥的基础设计提供可靠的依据。在结合Osterberg试桩法对地基承载力综合评定的基础上,对塔座、承台、桩基的设计做了介绍。

Using drilling,geophysical prospecting and laboratory test methods,topography,geolo-gical structure and formation lithology in the area of Suramadu Sea-Crossing Bridge are investigated and analyzed,and reliable basis are provided for the foundation design of the bridge.Design of pylon base,pile cap and pile foundation are introduced based on the evaluation of bearing capacity of ground base with Osterberg loading test method.
