The working mechanism of reinforced continuous cement-soil wall is described,and it is pointed out that the cement soil can share load and make contribution to the stiffness of continuous wall structure.

The construction application technology of cement-soil mixed continuous wall;

Application of the cement-soil diaphragm wall in the Fenhe project and the supervision control;

According to characteristic geological condition of Yangtze River Floodplain,composite retaining systems of soil nailing wall and cement-soil wall are used with the consideration of the experience,a simplified model for calculating is proposed along with calculation method and key construction of such composite retaining.

In soft soil area cement-soil wall has been used on deep foundation pit bracing,which not only has the advantage of good whole rigidity and less water leakage into the pit,but also saves time,is good for environment protection,and costs less money.
