摘　　要：为了探索强夯法对该类地基处理的适应性,结合某大型钾肥生产项目地基处理工程,针对改进的强夯法――强夯碎石桩法,进行了现场试验研究。平板载荷试验、动力触探和静力触探试验综合结果表明,强夯碎石桩法使处理后的地基承载力提高了2.4倍,有效加固深度超过6 m,对6～10 m深度处的土层的加固效果仍然比较显著。研究表明,处理该类地基,用碎石桩强夯法是适宜的,处理效果是显著的。The on-site experiment of gravel drainage pile and dynamic consolidation was carded out in a ground treatment of a large potash construction project in order to find out the applicability of the adopted method to this kind of ground. Results of the plate loading test, dynamic penetration test and cone penetration test show that the characteristic value of sub grade bearing capacity is raised by 2.4 times, and the significant consolidated depth reaches 6 m and even 10 m. Therefore, the research proves this method is suitable and appliable for treating the above kind of ground.
