“万丈盐桥”的建造机理及病害分析

Construction Mechanism and Damage Analysis of “Thousand-Zhang-long Salt Bridge”

通过阅读"万丈盐桥"的相关文献及资料,对其建造方法、建造机理及相关病害进行了综合阐述."盐桥"的建造采用了特殊的方法和材料,主要使用最佳含水率和最大干密度的岩盐填筑路堤,并在湖中卤水的作用下,使其达到作为路堤填料的抗压强度.岩盐微观结构密实、抗压强度较大,从材料的力学性能和微观结构来看,适合作为路堤填料.由于所处环境的影响,岩盐路堤的主要病害为溶蚀和地表水侵蚀,两种病害都由地下水或降水所致,所以主要以隔绝水的方法来防治两种病害.

The construction method,construction mechanism and related damages of the Thousand-Zhanglong Salt Bridge are illustrated through reading the relevant literatures and information.It was constructed with special methods and materials,and the rock salt with the best moisture content and the maximum dry density is used as the subgrade material,which can reach the compressive strength as a subgrade filler under the action of brine in the lake.The micro structure of rock salt is compact,so it is suitable as embankment filler.Due to the impact of the environment,The main damages of the road filled with rock salt are corrosion and surface water erosion,which are caused by groundwater or precipitation,so the prevention and treatment of two damages is to cut off water.
