压密注浆提高海淤软土承载性能研究

Study on Bearing Capacity of Sea Silt by Compaction Grouting

应用ANSYS软件对深层海淤软土压密注浆地基进行模拟分析,同时进行深层海淤加固参数的比选。按照理论研究的思路进行室外现场试验,通过取样试验、分层总和法计算和原位试验检测,深层海淤压密注浆对于有效提高承载力、减少沉降量具有很大的作用,加固效果较好。

ANSYS software is employed to simulate and analyze the compaction grouting foundation of deep sea silt and soft soil,and strengthening parameter of the deep sea silt and soft soil are selected at the same time. Based on sampling tests in-situ test and calculation of layered sum total method, it is verified that the compaction grouting for the deep sea silt and soft soil can play an important role in improving the bearing capacity, reducing settlements, so as to result in good strengthening effect.
