The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide.
標準貫入試驗（standard penetration test，SPT）是動力觸探的一種，是在現場測定砂或粘性土的地基承載力的一種方法。. 這一方法已被列入中國國家《工業與民用建築地基基礎設計規範》中。. 它利用一定的錘擊功能 ( 錘重63. 5kg ， 落距76cm ) ， 將一定規格的對開管式 ...
Advantages: Blow count frequency can be easily adjusted; Lifting height is constant; More easy to adjust and maintain its vertical position during testing. No jumping up of SPT sampler likes other hammers during lifting of hammer; Mechanical counter and further automation for penetration measurement is easier than other hammer.

Standard Penetration Test (SPT) is a simple and low-cost testing procedure widely used in geotechnical investigation to determine the relative density and angle of shearing resistance of cohesionless soils and also the strength of stiff cohesive soils. Driving sequence. Firstly, a borehole is extended to a predetermined depth.
The test will measure the resistance of the soil strata to the penetration undergone. A penetration emphirical correlation is derived between the soil properties and the penetration resistance. The test is extremely useful for determining the relative density and the angle of shearing resistance of cohesionless soils.
