车辆荷载对海塘堤顶路面及防渗墙影响三维分析

3D Analysis on Influence of Vehicle Load on Seawall-top Pavement and Diaphragm Wall

风电场建设期风机设备运输过程中,堤顶行驶的重件运输车辆可能会对堤顶路面结构和堤中防渗墙结构产生一定程度影响。以某风电场工程为例,对路面结构和防渗墙结构在有无车辆荷载作用下的情况进行了三维有限元分析,计算结果表明,加铺沥青混凝土路面能保证路面结构强度,且对防渗墙的应力控制有利。

In the transportation of draught fan and equipment during the construction of wind power station,the heavy transportation vehicles driving at the top of seawall maybe produce a certain influence on the seawall-top pavement structure and diaphragm wall structure. Taking a wind power station project as an example, the 3D finite element analysis is carried out for the pavement structure and diaphragm wall structure under the action of no vehicle load. The calculation result shows that overlaid asphalt concrete pavement can guarantee the pavement structural strength and is favorable for the stress control of diaphragm wall.
