基于能量法则计算黏性土不排水抗剪强度的方法
Calculation of undrained shear strength of clay based on the energy law
摘要
Abstract
The Bolton & Whittle resenting theory of energy law,in combination with the results of project SBPT in Bangladesh,is used to calculate the undrained shear strength (Cu) value of clay.Also,Marsland & Randolph method is adopted to calculate the value of undrained shear strength.It shows that result calculated by these two methods is very similar and reliable for calculation of Cu.It reveals that the Cu and limit pressure (pL) can be obtained from the plastic part gradient and intercept of the curve of total expanding pressure versus the logarithmic plane shear strain.In practical,the SBPT and the theory are suitable for the confirmation of undrained shear strength of clay soil.关键词
