RESEARCH ON THE CHARACTERISTICS OF THE SUBSIDENCE OF SOFT SOIL FOUNDATION IN YANGTZE RIVER DELTA AREA BASED ON ORIGINAL POSITION MONITOR

摘要

The sedimentation of soft-soil road of speedways directly influences the project quality. To scientifically calculate the velocity of fill placement, the completion time of pre-loading and pavement time of road surface, can effectively control the sedimentation during the construction of road surface and sedimentation after the construction, save investment on projects and enhance the utility quality of roads. While, the accurate calculation of fill replacement velocity, completion time of pre-loading and pavement time of road surface, must depend on reliable in situ motoring data and rational calculation method. Taking plenty of in situ motoring data of the speedways in the Yangtze River Delta area as the basis, we preliminarily sum up the statistic form of rules of soft-soil roadbed sedimentation in the Yangtze River Delta area.
