日本新干线静岗工务所采用矿渣对软土路基进行强化处理,取得了满意效果。施工方法是将路基面用反铲挖去300mm后用矿渣强化。这种快凝强化路基材料由水碎铁矿渣、早强水泥和粉末快凝剂构成。该方法的优点有:1.不必采用常规的夹层排水结构,可节省橡胶板等非织布材料;2.现场作业简单方便。这种混合材料摊平后仅需洒水,碾压即可;3.适用于要求快凝性的工程;4.
Japan Shinkansen Jinggang work using slag slag soft soil roadbed for reinforcement, and achieved satisfactory results. Construction method is to use the backfill roadbed surface to 300mm after strengthening with slag. This fast-curing subgrade material by the broken water iron slag, early strength cement and powder accelerator. The advantages of this method are as follows: 1. It is unnecessary to adopt the conventional sandwich drainage structure to save non-woven materials such as rubber plates; 2. The operation on site is simple and convenient. This kind of mixed material is only required to be sprinkled and rolled after being flattened; 3. It is suitable for projects that require fast coagulation;
