摘要
遮帘式板桩码头作为一种新型的结构型式,无成熟的理论及计算方法,常规的设计方法的不成熟及模型试验受到各种条件的限制,无法完全模拟现场实际工况。借助于有限元软件进行了三维及二维数值计算。从计算结果看,三维模型同二维模型比较接近。通过比较监测数据及不同的弹性模量计算结果,得到了合理的弹性模量值。进而计算考虑有墙后剩余水头及堆载的实际工况,考虑剩余水头后,其弯矩及轴力值与不考虑剩余水头其差值一般在8%～15%。考虑堆载后,前墙与遮帘桩正弯矩及后墙负弯矩有显著变化。
The covered sheet pile wharf is a new structural type.There is no perfect theories and design methods.The immaturity of the conventional design methods and model tests are subjected to various conditions and can not fully simulate the actual field conditions.The three-dimensional and two-dimensional models are calculated by use of the finite element software.The results of three-dimensional model and two-dimensional model are close to each other.By comparing different solutions of elastic modulus and monitoring results,the reasonable elastic modulus is obtained.The conditions are calculated considering the residual head after the wall and load.Considering the influences of residual head,the values of moment and tension are generally between 8%～15%.Considering the load,the moment has significant change in the front wall,covered sheet piles and back wall.
