摘要:
利用有限元分析原理,建立基于横观各向同性路基的三维仿真模型,分析在落锤式弯沉仪(falling weight deflectometer, FWD)脉冲动载作用下路基表面的弯沉,及不同深度处力学指标的变化,讨论土基材料横观各向同性对力学指标的动力响应影响.结果表明,路基弯沉峰值随距荷载中心点距离的增大而滞后,荷载中心点与距荷载中心200 mm处传感器点的滞后幅度最大(为60%);弯沉值随水平模量的增大而减小,最大减幅为21%;路基所受应力随深度的增加而减小,最大减幅为67%;水平模量的增大也会减小应力值,最大减幅为28%. 落锤式弯沉仪能较好模拟车辆移动荷载状况,反映实际路面受力情况,基于横观各向同性的土质路基,能有效地预测路基的使用性能.
Abstract:
The finite element analysis method was adopted and a three-dimensional simulation model was established for simulating dynamic response of transversely isortopic subgrade. Some mechanical response such as deflection and stress under the effects of Falling Weight Deflectometer were analyzed, and the impact that transversely isotropic subgrade material on the dynamic response was discussed. The results show that subgrade deflection peak is delayed with the increase of the distance from the center of the load, the largest delayed range is between the load center and the sensor point of 200mm away from the load center, deflection is decreased with the increase of horizontal modulus, the maximum reduction rate is 21%, subgrade stress is decreased with the increase of depth, the maximum reduction rate is 67%, increase of horizontal modulus will decrease the stress value, the maximum reduction rate is 28%. Falling Weight Deflectometer can simulate the vehicle moving load conditions, better reflecting the actual situation of the force to the road; and transverse isotropic can better forecast the performance of the subgrade.
