以临海某软基工程为例,对强夯施工参数进行了分析,通过建立强夯有限元计算模型,使用ADINA软件进行了数值模拟,得到最佳夯击能和合理的夯击次数,并对施工过程进行了现场监测,模拟数值与施工监测结果进行了比较,两者较为接近,软基处理结果表明,按照设计的强夯参数施工可较好达到规范要求,模拟计算结果有一定可靠性。
Taking Linhai a soft ground project as an example, the dynamic compaction construction parameters were analyzed. Through the establishment of finite element calculation model of dynamic compaction, numerical simulation was carried out by using ADINA software to get the best compaction energy and reasonable number of compaction. The construction process was monitored on site. The simulation results were compared with the construction monitoring results. The results of the soft foundation treatment showed that according to the design of the dynamic compaction parameters, the requirements of the code can be met well and the simulation results have certain reliability.
