摘要
采用强夯法新工艺对饱和软土地基进行了成功的加固处理。对强夯后地基土体的侧向位移、超静水压力的增长与消散规律等进行了现场试验研究。用静力触探实验和载荷实验对地基加固的效果进行了检验。探讨了强夯法有效加固深度的确定方法。实践表明,采用现场试验手段确定强夯法的有效加固深度及其他设计参数是可靠的。
A new technology of dynamic compaction method is successfully used to reinforce the saturated soft soil foundation.The field monitoring laws of lateral displacement of the foundation after dynamic compaction,the increasing and dissipation regularity of the excess pore water pressure are analyzed and discussed.The improvement effect is verified by static cone penetration test and loading test.The determination methods of effective reinforcement depth after dynamic compaction are put forward.The experiment shows that such field-testing methods as static cone penetration test and pore water piezometer test to determine the effective reinforcement depth after dynamic compaction and other design parameters are reliable.
