Prefabricated vertical drains (PVD) are usually used for reinforcement and dewatering of soft clay foundation. According to the combining manner of the core board and filter
PVD can be divided into two types as separate shape PVD and integral shape PVD. A series of tests were carried out to compare the difference of the two types of PVD in physical property
mechanical property and hydraulic property. The results indicate that comparing to separate shape PVD
the integral shape PVD has higher tensile strength
