Embodiment Construction
[0034] Below in conjunction with accompanying drawing and specific example, further illustrate the present invention, should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalents of the present invention Modifications in form all fall within the scope defined by the appended claims of this application.
[0035] see figure 1 As shown, the present invention discloses a method for in-situ evaluation of soft soil consolidation coefficient based on a spherical full-flow penetrometer. The full-flow penetrative ball probe 1 has nine 2-hole pressure sensors, which are symmetrically distributed . The surface of the pore pressure sensor is wrapped with a pore pressure filter ring, which can prevent soil particles from entering the pore pressure sensor and affecting the test results during th...
