相对密实度对沈阳砾砂峰值强度影响
Tests on the influence of the peak strength of the gravelly sand in Shenyang area considering different relative densities
摘要
Abstract
It is obvious that the relative density Dr changes greater than other parameters of soils during the disturbance of excavation.The parameters of Duncan-Chang model are obtained according to the results of triaxial consolidation drained shear tests on the gravelly sands of different relative densities in Shenyang region under different confining pressures.Then,the influence rule between the peak strength and the relative density Dr are discussed.The fitting result shows that the relation between M which is a parameter related to and Dr is approximately linear.Then,the relation between and Dr is established.As well,it has little influence of l which is also a parameter related to and Dr by Dr.It means that,approximately,l does not change when Dr changes.关键词
