杭州市江东大桥位于钱塘江强涌潮河段,桩基采用大直径超长钻孔灌注桩,持力层为极软岩,桩底采用后压浆技术。对杭州市江东大桥主桥桩基的设计作了简要介绍,对桩基持力层的选择、单桩承载力的确定等有关问题进行了探讨,并介绍了主要计算结果。
Jiang Dong Bridge is located in strong-tidal aera of Qiantang River in Hangzhou city,The ultra-long bored piles with large diameter are adopted for the ultra soft support earth layer with the post-grouting technology.The design of pile foundation of the main bridge was introduced,the choice the bearing stratum,the determination of the bearing capacity and the main calculation results are discussed.
