Fill subgrade retaining structure for deep overburden layer landslide section and construction method
The invention discloses a fill subgrade retaining structure for a deep overburden layer landslide section. The fill subgrade retaining structure comprises front-row anti-slide piles and rear-row anti-slide piles that are arranged on the two sides of a fill subgrade respectively. The anti-slide piles penetrate through an overburden layer landslide sliding face and stretch out of the ground, the front-row anti-slide piles and the rear-row anti-slide piles are arranged in a staggered mode in a direction of the center line of the fill road; pile top longitudinal joists connected with the front-rowanti-slide piles are longitudinally arranged at the tops of the anti-slide piles, and transverse connecting beams and oblique connecting beams are arranged between the pile top longitudinal joists. Foundation widening type reinforced concrete thin-wall retaining walls are longitudinally arranged at the tops of the pile top longitudinal joists respectively, and opposite-pull threaded steel bars used for fixing the retaining walls are arranged between the thin-wall retaining walls. The fill subgrade retaining structure has the advantages of being economical, reasonable, convenient to construct,clear in structural stress, capable of effectively controlling subgrade settlement and horizontal displacement, capable of reducing engineering cost and the like, safety of the deep landslide sectionfill subgrade is guaranteed and reference is provided for design and construction of the deep landslide section fill subgrade.
本发明公开了一种深厚覆盖层滑坡地段填方路基支挡结构，包括分别设置于填方路基两侧的前排抗滑桩和后排抗滑桩，抗滑桩均穿过覆盖层滑坡滑动面且支出地面，前排抗滑桩和后排抗滑桩沿填方路道路中线方向交错布置，抗滑桩顶部纵向设置有连接排抗滑桩的桩顶纵向托梁，桩顶纵向托梁之间设置横向连系梁和斜向连系梁；桩顶纵向托梁顶部分别纵向设置基础加宽型钢筋混凝土薄壁挡土墙，薄壁挡土墙之间设置有用于固定挡土墙的对拉螺纹钢筋。本发明具有经济合理、施工方便、结构受力明确、有效控制路基沉降及水平位移、降低工程造价等特点，确保深厚滑坡地段填方路基安全，为深厚滑坡地段填方路基设计与施工提供参考。
