查询词典 pedestal pile

Better numerical prediction of the distributions of shear forces and bend moment within the pile group has also been obtained with the consideration of many stochastic parameters such as the soil properties of sea warf, seismic properties, etc. And then we analyze the dynamic nonlinear seismic pile-soil interaction in sea warf as an example to apply the software of ANSYS to the assessment of the dynamic interaction of soil-structure in the harsh situation of random earthquake. And then we denoted that the soil-pile interaction is too difficult to be expressed in equations because the non-linear interaction between soil and pile.
