Construction Control and Survey Data Analysis of Weak Subgrade

Problems existing in weak subgrade construction and the disposal and control of weak subgrade are in- troduced.A new better construction technique is put forward based on the underlying principle of vacuum stacked combined preloading technique in weak subgrade treatment.The linear regression equation with one unknown quan- tity indicating the linear relation between the horizontal movement and vertical deformation of the weak subgrade is deduced.The results show that the methods and model have valuable and pratical significance for the construction of weak subgrade.
