红砂岩粗颗粒土满夯冲击能量消耗研究

Research the Impact Energy Consumption of Dynamic Compaction on Full Ramming About Red Sandstone Coarse Particle Soil

利用室内击实仪模拟满夯,研究红砂岩粗颗粒土在满夯作用下的土体对能量吸收和土体的加固效果,满夯锤印搭接变化和间隔满夯与搭接满夯方式对土体吸收夯击能和满夯效果的影响。文中通过研究0,1/4,1/2三种搭接锤径下的满夯土体沉降和1/4锤径下搭接满夯与间隔满夯的沉降差值对比。研究红砂岩粗颗粒土满夯冲击能量消耗规律得出相关结论,通过结论对满夯施工提供参考意见同时提出新的带解决的实际问题。

Using indoor compaction instrument to simulate full dynamic compaction,it can be researching that the action of energy absorption and soil reinforcement effect of the red sandstone coarse particle soil in full dynamic compaction,and the changing of overlap diameter about the pounder and interval and continuous full dynamic compaction have an effect on soil absorbing the tamping energy and full temper effect. Research the settlement of soil in the cases of overlap diameter of the pounder--0,1/4,1/2 and the comparison on settlement of soil in 1/4 overlap diameter interval and continuous full dynamic compaction.Research the impact energy consumption of dynamic compaction on full ramming about Red sandstone coarse particle soil and get the conclusion.Provide reference opinions on dynamic compaction construction on full ramming and bring out new hanging actual problems.
