Treatment method for filling loess mudstone landslide cracks with fluid soil
The invention relates to a treatment method for filling loess mudstone landslide cracks with fluid soil, which comprises the following steps: (1) surveying a landslide mass, and determining the position, length, depth and width of a large landslide crack; (2) according to the depth and width of the cracks, the landslide mass cracks are divided into deep cracks and shallow cracks; (3) excavation is conducted after excavation sections are selected according to classification, and classification treatment is conducted; wherein during deep crack treatment, shallow excavation is conducted firstly, then a fluid-state soil material is adopted to conduct pouring, filling and backfilling on the crack, after solidification is completed, an excavated trapezoidal groove slope surface line is treated to be in a step shape, and then part of soil is backfilled, tamped and excavated in a layered mode; during shallow crack treatment, direct excavation is performed, and then layered backfilling and tamping are performed; the compaction degree is controlled to be 90% or above; (4) recovering vegetation; (5) later maintenance. Rainfall infiltration can be effectively reduced, and the stability of the landslide is improved.
本发明涉及一种使用流态土填补黄土泥岩滑坡裂缝的处理方法，该方法包括以下步骤：⑴勘察滑坡体，确定较大滑坡裂缝位置、长度、深度及裂缝宽度；⑵根据裂缝的深度和宽度，将滑坡体裂缝分为深层裂缝和浅层裂缝两类；⑶根据分类选定开挖段之后进行开挖，并分类处理；其中：深层裂缝处理时先浅开挖再采用流态土材料对裂缝进行灌注填补回填，待固结完全后，将已开挖梯形槽坡面线处理成阶梯型，再分层回填夯实开挖部分土体；浅层裂缝处理时直接开挖后分层回填夯实；压实度控制在90%以上；⑷植被恢复；⑸后期维护。本发明可有效减少降雨入渗，并提高滑坡自身稳定性。
