开山填海地层地质复杂、欠固结,承载力低,均匀性差,采用强夯加固是一种经济、安全的优选方案。广东珠海化工品仓储项目强夯工程加固面积大,为183702m2;采用的夯击能高,最大夯击能为10000kN·m;加固效果佳,加固后的地基承载力特征值fak≥300kPa,压缩模量Es≥12MPa,有效加固深度至岩层基面或不小于15.0m;从试夯、设计、施工、检测至评价资料齐全,是一项成功的工程实例,对于高夯击能在开山填海地层的的应用具有一定借鉴意义。
The geological reclamation of the reclaimed sea formations is complex, underconsolidated, with low bearing capacity and poor uniformity. It is an economical and safe optimization plan to adopt the dynamic consolidation method. Zhuhai, Guangdong Zhuhai chemical storage project dynamic consolidation project to reinforce a large area of 183702m2; the use of the ram impact energy, the maximum impact energy of 10000kN · m; reinforcement effect is good, the reinforced foundation bearing capacity characteristic value fak ≥ 300kPa, compression mode The amount of Es ≥ 12MPa, the effective depth of reinforcement to the basement of the rock or not less than 15.0m; from the rammer, design, construction, testing to complete evaluation of the data is a successful example of the project, The application of a certain reference.
