The vaccum preloading and broken stone pile method is an economic and effective method for quickly consolidating the weak reclamation foundation,and the method can improve the bearing capacity of foundation and reduce the foundation settlement after completion of project.

The application of vacuum-surcharge preloading in foundation treatment for electric power plant;

To prove its efficiency,a test on situ also conduced with vacuum-surcharge preloading saturated soil treatment.

Based on the field experiment and research work carried out in the Ri Zhao dock in Shan Dong province,the mechanism of improvement of soft subgrade with the vacuum-surcharge preloading method is discussed.

Boundary effect of the method combined vacuum and surcharge preloading and influencing factors thereof;

Assessment of effect of ground improvement for hydraulic structure using combined vacuum and surcharge preloading;

The paper studies the consolidation mechanism and effect of vacuum-heaped preloading in a soft foundation treatment project and makes comparison with that of the vacuum preloading and heaped preloading.

Simplified nonlinear analysis of subsoil improved by vacuum combined with surcharge preloading;

Considering the special engineering geology condition of soft soil foundation in Qingdao seashore expressway,vacuum preloading、surcharge preloading、vacuum combined surcharge preloading and dynamic compacted stone pier are adopted to strengthening soft soil foundation.

Vacuum preloading and Vacuum combined Surcharge preloading are effective methods to improve soft foundation.
