PILE FOUNDATION PROPERTY OF VIBRO PILE IN EXPANSIVE SOIL OF HEISHAN AREA

Expansive soil 'in Heishan area. is different from general clay. The lateral friction resistance is relative-1y large, while the end-bearing resistance is relatively small, when.putting vibro pipe in such soil. On the basis of collection of data from many dynamic exploration and dynamic test report on pile, the regionally empirical for-mutation showing the relation betwen dynamic exploration times and lateral friction resistance and end-bearing resistance of pile is obtained, pile foundtion propeity of such pile in expansive soil is also analyzing.
