Deep ramming treatment method for large-thickness collapsible loess
The invention provides a deep ramming treatment method for large-thickness collapsible loess. The method comprises the following steps: calculating the tamping energy of each point and the falling distance of a tamping hammer according to the formula by adjusting the spacing of tamping points, optimally configuring a main tamping point and an auxiliary tamping point and according to the effective depth required to be reinforced, tamping the main tamping point firstly and then tamping the auxiliary tamping point according to the calculated tamping energy of each tamping point and the falling distance of the tamping hammer. The loess treatment depth can reach 10 m or above, the collapsibility of new loess foundations with the depth of about 10 m can be remarkably weakened and eliminated, the problems that domestic large-thickness collapsible loess foundations are insufficient in tamping treatment depth and insufficient in design and construction experience are solved, new possibilities are provided for current first and second building foundation form selection, and extremely high practicability is achieved.
本发明提供了一种大厚度湿陷性黄土深层夯击处理方法。所述方法通过夯点间距的调整布置，主夯点和副夯点的优化配置及根据需要加固的有效深度按照公式计算出各点的夯击能和夯锤的落距，按照计算出来的各夯点击能和夯锤落距，先针对主夯点进行夯击，再针对副夯点进行夯击。其黄土处理深度可达10m及以上，能显著减弱及消除10m左右深新黄土地基湿陷性，弥补了国内大厚度湿陷性黄土地基夯击处理深度不够，设计施工经验不足的问题，也为当前甲、乙建筑地基形式选择提供了新的可能，具有极强的实用性。
