Abstract | The implementation of deep mixing method (DMM) of soft ground improvement technique raises the possibility of increasing the initial water content of the soft ground before mixing the chemical stabilizer (either cement or lime). The effects of high remolding water content on the undrained shear strength and compressibility of the cement treated soft Bangkok clay were investigated using the unconfined compression (UC) and oedometer test, respectively. The UC strength response of cement treated clay depends on the three main variables consisting of cement, clay water content, and curing time. From the results of the analysis, the strength of cement treated soft Bangkok clay can be predicted by using the lumped parameter of clay water content and cement content ratio, wc/Aw. The strength increases with decreasing we/Aw. The post yield compression behavior of cement treated soft Bangkok clay depends only on the amount of cement, while the effect of the initial clay water content is to increase the initial void ratio that could reduce the yield stress. The post-yield compression lines can be normalized into a single compression line by introducing a parameter 1 +e100. Useful empirical relations are presented to predict the strength and deformation of DMM improved soft Bangkok clay. |
