摘要
文中结合埃克森美孚惠州化工综合体项目试夯工程,开展了深厚软土区域不同能量级的强夯系列试验与对比研究.文中通过平板载荷试验、孔隙水压力监测、重型动力触探试验及瑞利波试验对比同一能级强夯前后土层力学性质的变化,分析各能力的强夯处理效果,给出了后期强夯法加固地基土压缩模量.
Abstract
The article combines the trial compaction project of ExxonMobil Huizhou Chemical Complex to conduct a series of dynamic compac-tion tests and comparative studies on deep soft soil areas with different energy levels.The article compares the changes in the mechanical prop-erties of soil layers before and after dynamic compaction at the same energy level through plate load tests,pore water pressure monitoring,heav-y dynamic penetration tests,and Rayleigh wave tests,analyzes the effectiveness of dynamic compaction treatment for each capacity,and pro-vides the compressive modulus of foundation soil reinforced by later dynamic compaction methods.This can provide reference for the design,monitoring.
