Description

[0001] technical field [0002] The invention belongs to the field of civil engineering, and relates to a variable-rate pore pressure static penetrating test device. [0003] Background technique [0004] Pore ​​pressure static penetration testing technology refers to the use of pressure devices to press the penetration rod with the contact probe into the test soil layer, and test the cone tip resistance, side wall friction resistance and pore water pressure of the soil through the measurement system. Determine some basic physical and mechanical properties of soil, such as soil deformation modulus, soil allowable bearing capacity, etc. The international technology of pore pressure static penetration testing has a history of more than 30 years. Hole pressure static penetration test technology is widely used in the world, partially or completely replacing drilling and sampling in engineering investigation. At present, electrical static penetration testing is widely used in ...
