摘要
高速公路软基施工中存在着盲目性 ,而施工的监测反馈通常是一种事后控制的方法。提出了一种动态仿真控制的方法 ,在每一级 (或几级 )填土后 ,利用监测数据反算土参数 ,模拟即将进行的施工过程 ,考虑强度增长 ,进行仿真计算 ,找到最优施工方案 ,实现对公路软基整个施工过程进行动态仿真控制。将这种方法应用于广 (州 )梧 (州 )高速公路的施工中 ,有效地避免了施工的盲目性 ,取得了很好的效果。
The technicians always treat soft foundation in road construction blindly and the feedback monitor in road construction is a sort of after-action control. In order to solve this problem, a method using dynamic simulation control in road construction, which is successfully applied in the construction of the Guangwu freeway, was put forward.In order to control the road construction in anticipation, the data of pore-water pressure was analysed to get consolidation degree in time after stuffing each layer of soil. Considering the strength increase of the soft soil, the construction to be done was simulated.Many projects were constituted, then the most suitable project was choosed to arrange the construction. Keeping up this procedure, dynamic simulation control in whole process of road construction is realized. Blindness in the construction can then be avoided.
