Settlement Control Research of Soft Soil Subgrade Based on Long Qi Bay Project
Jin Zhou Long Qi Bay distributes in different areas of shallow marine sediments, it is necessary to predict and control the settlement of soft soil subgrade. The authors have observed the settlement using the level acquiring horizontal basin maps of vertical settlement and transformed them to ideal horizontal basin maps equivalently and then made a comparision. We have calculated the coefficients of earthwork calculation of settlement reversely. The results have shown that the shapes of the settlement curves of numerical simulation are very similar to those measured, the maximum settlements are very close, which further has shown that stone filled treatment subgrade has received significantly control of settlement and the structure has been significantly strengthened. The reverse calculation of the coefficients has enhanced the applicability of the models which can be adjusted according to the soil of different regions.
