| Abstract: | The instant surface wave testing is characterized by fast velocity,high precision and low requirement for site.Using the suitable parameter and method,we can well prospect the distribution of composition material,get on with the site soil classification,site evaluation and the liquidation analysis of saturated sand-soil,provide the physical mechanical parameters of alluvium and diluvium beds for engineering design and construction,and provide the excelent period of site for the antiseismic design,etc.The application of instant surface wave method in the prospecting of alluvium and deluvium can compensate and enrich the prospecting data,improve the prospecting precision and shorten the period of engineering prospecting. |
