EXPERIMENTAL ANALYSIS OF THE INFLUENCE OF VIBRATION DURING 10 000kN·m HIGH ENERGY LEVEL DYNAMIC COMPACTION

摘要: 通过在沿海某碎石回填地基上成功实施的10 000kN.m高能级强夯系列试验,为10 000kN.m高能级强夯的设计、监测和检测提供了依据。根据对试验过程中地面振动加速度的监测分析,得到了碎石土地基上10 000kN.m强夯施工时的加速度衰减方程和传播特点,可用于分析高能级强夯地基处理的环境效应。Abstract: 10 000kNm energy levels of experiment dynamic compaction are successfully put in practice on a rubble fill site in a coastal area. The experiment provided the parameters for the design, construction and detection of 10 000kNm dynamic compaction. The monitoring results of ground vibration acceleration were analyzed. The attenuation equation and transmit characteristic of 10 000kNm dynamic compaction on rubble fill site during 10 000kNm were acquired. It can be used to estimate the environment affect during high energy level dynamic compaction.
