一、动力固结法与振动压实法的应用英国格-基思-内特尔福兹钢铁公司(GKN),最近在萨里一处工业用场地的土层加固工程中采用了两种加固方法:动力固结法和振动压实法。该场地将被用来修建废金属仓库与加工中心,包括约2500平方米的工区与办公地点,另外还有13000多平方米的露天堆栈、载重场、行车道和停车场。该场地原为金沙矿井,后被工业废碴与一般垃圾回填,回填层厚约6米。有14750平方米的场地要求达到11万牛顿/平方米的承载力,而停车场和车间区所需的承载力较低。加固工程完成时,在600毫米最小深度内地平面以下便形成简单的和比较轻型的基础,而不是桩基或其他深基。
I. APPLICATION OF DYNAMIC CONSOLIDATION AND VIBRATION AND COMPACTION TECHNIQUE Great Britain-Keith-Nertel Foz Steel (GKN) recently adopted two types of reinforcement in a soil reinforcement project at an industrial site in Surrey. Methods: Dynamic consolidation and vibratory compaction. The site will be used to build a warehouse and processing center for scrap metal, including about 2,500 square meters of work area and office space, as well as more than 13,000 square meters of open-air stacks, load-bearing yards, carriageways and parking lots. The site was formerly known as the Jinsha Mine. It was backfilled with industrial waste and general waste. The backfill was about 6 meters thick. A site of 14,750 square meters requires a bearing capacity of 110,000 newtons per square meter, while the parking lot and the workshop area require a lower carrying capacity. When the reinforcement works are completed, a simple and relatively lightweight foundation is formed below the ground plane at the minimum depth of 600 mm, instead of the pile foundation or other deep foundations.
