格构加固边坡的设计与施工ppt课件

高陡边坡加固中被广泛采用，其护高陡边坡加固中被广泛采用，其护坡到达既美观又平安的良好效果。坡到达既美观又平安的良好效果。格构的主要作用是将边坡坡体的格构的主要作用是将边坡坡体的剩余下滑力或土压力、岩石压力分剩余下滑力或土压力、岩石压力分配给格构结点处的锚杆或锚索，然配给格构结点处的锚杆或锚索，然后经过锚索传送给稳定地层，从而后经过锚索传送给稳定地层，从而使边坡坡体在由锚杆或锚索提供的使边坡坡体在由锚杆或锚索提供的锚固力的作用下处于稳定形状。因锚固力的作用下处于稳定形状。因此就格构本身来讲仅仅是一种传力此就格构本身来讲仅仅是一种传力构造，而加固的抗滑力主要由格构构造，而加固的抗滑力主要由格构结点处的锚杆或锚索提供。普通提结点处的锚杆或锚索提供。普通提及到的格构加固技术是一种广义的及到的格构加固技术是一种广义的术语，它包含了格构本身和锚杆术语，它包含了格构本身和锚杆(索索)两部分。两部分。拱或钢筋混凝土(如图73所示)。4)弧型：按顺边坡倾向设置浆砌块石或钢筋混凝土条带，沿条带之间向上设置弧型浆砌块石拱或钢筋混凝土(如图74所示)。边坡体自重、静水压力、浸透压力、孔边坡体自重、静水压力、浸透压力、孔隙水压力、地震力等。对于整体稳定性隙水压力、地震力等。对于整体稳定性好，并满足设计平安系数要求的边坡，好，并满足设计平安系数要求的边坡，可采用浆砌块石格构进展护坡。采用阅可采用浆砌块石格构进展护坡。采用阅历类比法进展设计，坡度普通不大于历类比法进展设计，坡度普通不大于35，即即1 1.7。当边坡高度超越。当边坡高度超越30m时，须时，须设马道放坡，马道宽设马道放坡，马道宽1.53.0m，如图，如图75所示。所示。性进展锚固荷载反算。性进展锚固荷载反算。假设T1=T2=T，那么格构梁上的荷载均匀分布，有p1=p2=p=T/l (7.6)112221(2)/(2)/pTTlpTTljgmaxMmax0.55agRRmin0.15%20max(1 0.5)ajgjgcR
