FULL-SCALE LARGE FIELD TESTS OF PILE-RAFT IN SOFT SOIL AREA
-
摘要: 结合某造船基地船台、横移区大型桩筏基础原位载荷试验,对试验过程中筏板变形、桩顶反力、不同深度土中附加应力、深层分层沉降进行详细监测,通过实测数据统计分析得出桩筏基础的一些受力变形规律,同时也对试验中一些问题进行讨论,指出现有监测设备存在的问题,积累了软土地区桩筏基础试验经验。Abstract: An in-situ test of a supergiant pile-raft was performed.During the experiment,a great variety of monitoring instruments were embedded to monitor the deformation of the raft,reaction of the piles,soil pressures in several vertical and laminar displacements.Some important rules about pile-raft foundation are achieved,and some questions of the testing are discussed.Also some shortages of the monitoring instruments are presented.
