摘要
厦漳跨海大桥主墩承台采用钢板桩围堰施工。介绍了其主墩承台的施工工艺,并从施工过程中的3个控制工况对其钢板桩、围檩及支撑进行了详细的设计计算;从基坑坑底涌砂,钢板桩最小入土深度及基坑抗隆起稳定安全系数3个方面对基坑的稳定性进行了验算。
The main piers of Xiazhang sea-crossing bridge are constructed by steel sheet pile cofferdam.This article introduces the construction technology of the main pier and expounds the design and calculation of the steel sheet pile and supporting in detail from three control conditions of the construction process.The three factors of The foundation pit stability is checked based on the burst from pit,the minimum depth in soil and pit heave-resistant stability safety factor.
