WebThese results could be explained in the framework of poroelastic theory. Although it is not possible to determine Skempton’s B-parameter ( Skempton, 1954) and the Biot-Willis poroelastic parameter ( Biot and Willis, 1957) separately from multistep strength tests, the product of both parameters can be derived from the test results. WebThe Biot-Willis coefficient is a key component associated with the effective stress field, where it represents the proportion of fluid pressure that counteracts the confining stress. …
