Foundation Settlement Feature Analysis And Development, Subsidence Simulation Test System

In this paper, FEM simulation of the consolidation settlement of foundations is conducted, with the help of the Small Strain Elastic 2 (SSE2), which is a part of the Large Strain Consolidation Finite Element Analysis (LSCFEA) program. The curves of the consolidation settlement in soft clay base of flood land are gained, which compare the effect of sand drain. The settlement-time curves in different period are also gained, which increase the height of embankment to 8m,based on the test data of hang-yong highway. Furthermore, the consolidation settlement characters of these entity engineering are analyzed, and, the variation rules of the rate of grade and degree of the curves in different period in the whole section, the maximal settlement and the liner regression relations between the rate of grade and degree are calculated.According to the module of the consolidation settlement curves and their characteristic relations, we design the simulation system of the large test platform, this paper introduce the whole design thought of the test platform, and emphasis on the analysis design of the critical segment in the design procedure. And, the settlement simulation adaptability of the integer test platform is also analyzed. At the same time, the feasibility of study conclusion is confined.
