    DISCUSSION ABOUT GROUND-TREATMENT METHOD FOR MASSIVE-FILL AT THE SHORE IN SHENZHEN

    • 摘要: 在上部为块石填土、下部为相对软弱的粘性土,地下水与海水相通的地区进行大型工程建设,主要和重要建(构)筑物采用桩基础是安全可靠的措施,采用潜孔锤引孔穿过块石填土,往孔内回填碎石,然后打H型钢桩,在深圳某电厂地基处理中获得了较好的效果。一般建(构)筑物地基采用强夯处理是经济可行的,采用夯击能为3 500 kN-m的强夯法进行地基处 理,试验证明易于施工、处理后的地基承载力可满足一般建(构)筑物的要求。

       

      Abstract: It is a safety and reliable step that the main buildings&constructions of large-engineering adopt pile-foundation in the engineering-geology condition as follow: the upper part consist of massive-fill, the lower part consist of soft clay, groundwater and seawater communicate with each other. In some power plant in Shenzhen city, making lead-holes in the massive-fill using dive-hole hammer, and return filling gravel into the lead-holes,then driving H-pile, using this work process obtained so that result in ground-treatment; and adopting dynamic compaction for ground is economical and feasible step, it is proved by the test that 3 500 kN穖 compacting-energy is easy for construction and suitable for ground bearing capacity of general buildings & constructions.
