Filling side slope anchor rod frame beam supporting method based on dynamic compaction reverse excavation treatment
The invention relates to a filling side slope anchor rod frame beam supporting method based on dynamic compaction reverse excavation treatment. According to the scheme, the method comprises the following steps that S10, layer-by-layer overfilling is carried out on the edge of a side slope and the portion poor in dynamic compaction reinforcing effect to form the filling side slope; s20, dynamic compaction reinforcement treatment is conducted on the fill forming the fill side slope through overfilling layer by layer; s30, carrying out an on-site direct shear test and an anchor rod basic test; s40, after the test is qualified, the filling side slope subjected to dynamic compaction reinforcement treatment is reversely excavated step by step to form a preset slope ratio; s50, according to the height of the slope, the grade number and the supporting type of the slope are set; and S60, frame beam construction is conducted on the multi-stage side slope. According to the method, the steep slope rate can be formed, the requirement for construction land is met, dynamic compaction can be fully utilized for pre-consolidation of the filler, post-construction deformation is reduced to the maximum extent, the requirement for immediately carrying out engineering construction is met, and the problems that soil pressure is too large due to filling soil sedimentation, an anchor rod is subjected to bending shear, and hole collapse is caused during anchor hole drilling can be solved.
本发明涉及基于强夯反开挖处理的填方边坡锚杆框架梁支护方法，该方案包括以下步骤：S10、对边坡边缘和强夯加固效果欠佳部位进行逐层超填形成填方边坡；S20、逐层对超填形成填方边坡的填方采取强夯加固处理；S30、开展现场直剪试验和锚杆基本试验；S40、试验合格后，逐级将强夯加固处理后的填方边坡反开挖形成预设坡率；S50、根据边坡高度设置边坡级数和支护类型；S60、对于多级边坡，在边坡上进行框架梁施工。本发明既能形成较陡坡率，满足建设用地需求，又能充分利用强夯对填料进行预固结，最大限度地减小工后变形，满足立即开展工程建设的需求，还可减轻填土沉降导致土压力过大、锚杆受到弯剪、锚孔钻进时蹋孔等问题。
