某填海造陆工程软基处理加固效果分析

Analysis on Reinforcement Effect of Soft Clay Improvement Foundation in Land Reclamation Project

介绍了某填海造陆工程预压法加固吹填淤泥与海相沉积淤泥软基处理效果检测方案,对加固前后淤泥的物理力学性质与强度进行了整理分析,结果表明:①软基处理加固前应充分考虑晾晒与自重固结作用对吹填淤泥固结性状的影响;②加固前吹填淤泥的物理力学性质明显差于海相沉积淤泥,加固后除十字板剪切强度远小于后者外,前者各项指标的改善程度均优于后者,两者物理性质十分接近,软基处理效果明显.

Detection scheme of reinforcement effect of dredged fill and marine deposit silt foundation improvement by surcharge preloading in land reclamation project was introduced,according to the analysis on physical and mechanical properties and strength of silt fore-and-aft improvement, the results show that： ①The influence of sunning and self-weight consolidation on consolidation behaviors of dredged fill should be considered adequately before soft clay foundation improvement; ②The physical and mechanical properties of dredged fill is significantly worse than marine deposit silt betore soft clay foundation improvement,however,after soft clay foundation improvement, the improvement effect for all physical and mechanical indices of the former is superior to the latter except vane shear strength,and both physical properties are very close,which has an obvious reinforcement effect.
