FORECAST AND PREVENTION OF ENVIRONMENT DISEASSS CAUSED BY PILING
沉桩引起环境病害的预测和防治

The mechanism and the regularity of the earth vibration and the soil extrusion caused by pile driving (pressing) are analyzed, the forecast criterion, method and the corresponding preventive measures of the environment disease are also suggested. Combined with example project, semi-analytic FEM and the simplified practical calculation method are put forward. These methods are compared with the in-situ measurement, and they can satisfy the engineering precision. The conclusion of this paper can be consulted by engineers in construction enterprises and designer for reference.
