锚拉式钢板桩坞壁原体观测研究

In situ test of the anchored steel sheet pile dock wall

对外高桥造船基地二座特大型干船坞坞壁结构的受力状态和原位测试成果进行了分析研究,以便为上海地区软粘土中单锚钢板桩结构设计积累经验。通过对原位监测数据的筛选分析表明,上海地区软粘土所具有的流变特性对板式挡土围护结构的受力变形具有重要且共同的影响。对今后上海地区软粘土中单锚钢板桩结构设计提出了建议。

Study has been carried out on structural state of the dock wall of two very large dry docks in Waigaoqiao Shipbuilding Base, so as to collect data for improving design of single anchored steel sheet pile retaining wall in very soft clay of Shanghai area. It is obvious by analyzing data from observation in situ that the rheologic characteristics possessed by the soft clay of Shanghai area exert important and common influence on retaining structure of plate type. Improvement later on has been proposed for design of such structure.
