【摘要】 格构梁与锚管注浆复合结构是治理滑坡的一种有效措施。文中系统阐述了格构梁与锚管注浆复合结构的作用机理,将锚管对格构梁的作用视为集中力作用,集中力的大小按照剩余推力法计算,将格构梁简化为受多个集中力作用的弹性地基梁,分析了格构梁的内力并计算出梁的配筋。通过现场试验,得到注浆浆液配比以及加固影响范围,并据此对常张高速公路K 129裂隙岩体边坡进行加固处理,取得了满意的结果。更多还原

【Abstract】 The lattice beam and anchor pipe grouting composite structure is an effective engineering measure in landslide control.In this article,the mechanism of lattice beam and anchor pipe grouting was expounded.The effect of anchor pipe on the lattice beam was regarded as concentrated force,and the force was derived from residual thrust method.The lattice beam was regarded as Winkler elastic foundation.The internal force and reinforcement of beam were calculated.According to in-situ grouting experiment,the mix proportion and strengthening area of grout were got.The methods and steps of anchor pipe grouting were applied to fractured rock slope reinforcement.The K129 slope of ChangZhang highway was an example, lattice beam and anchor pipe grouting was applied to the control project design and the effect of slope reinforcement is satisfactory.更多还原
