The in-situ test techniques are the effective methods to get the information of soil stratum. All kinds of in-situ test develop towards muti-founctional apparatus, which obtain much information in a term test. For instance, it can be used to measure the parameter of the pore pressure、temperature、wave velocity、lateral stress、resistivity and radioactivity in the top of CPT. In order to ensure the construction quality rapidly, exactly and continuously, the TDR test was developed, which can get the water content and dry density. A series of measure apparatus were developed to estimate the quality of the big diameter cast-in-place and the pile foundation under the building internationally, for example the pore probing, the concrete penetrometer and the thermal exchange pile.

The lab’s aim is to grasp the in-situ test technical direction internationally and organize a workshop to study the in-situ test techniques, which will make be important base fulcrum of geotechnical be outop inland and be advanced overseas.
