Soft soil area road time sequence InSAR deformation estimation method considering cyclic load
The invention provides a soft soil area road time sequence InSAR deformation estimation method considering cyclic load. The method is oriented to soft soil area road deformation monitoring under the influence of long-term cyclic load of vehicles, based on the multi-temporal InSAR technology, time sequence deformation modeling and model parameter calculation are carried out respectively, and finally the soft soil area road time sequence deformation is estimated through the obtained deformation parameter solution. In the time sequence InSAR modeling link, cyclic load plastic strain model components are introduced into an InSAR deformation model, and a soft soil area highway time sequence InSAR deformation model considering vehicle cyclic load influence is established. The method overcomes the defect that the influence of the vehicle load is ignored in a traditional InSAR monitoring method, can accurately estimate the time sequence deformation of the road in the soft soil area under the influence of the long-term vehicle cyclic load, widens the application field of the InSAR technology, and can also provide reference for road deformation analysis and interpretation and deformation prediction and early warning under the influence of the vehicle load.
本发明提供一种顾及循环荷载的软土地区公路时序InSAR形变估计方法。本方法面向车辆长期循环荷载影响下的软土地区公路形变监测，基于多时相InSAR技术，分别开展时序形变建模和模型参数解算，最终通过获取的形变参数解估计软土地区公路时序形变。时序InSAR建模环节将循环荷载塑性应变模型分量引入InSAR形变模型，建立了一种顾及车辆循环荷载影响的软土地区公路时序InSAR形变模型。本方法克服了传统InSAR监测方法中忽略了车辆荷载影响的缺陷，可准确估计软土地区公路受长期车辆循环荷载影响下的时序形变，拓宽了InSAR技术的应用领域，也可为车辆荷载影响下的公路形变分析解译与形变预测预警提供借鉴。
