Design method of arched retaining wall
The invention discloses a design method of an arched retaining wall, which comprises the following steps: selecting the type of the arched retaining wall according to on-site topographic conditions; a three-hinged arch model is adopted, constraints are arranged at arch shoulders and arch feet at the two ends, the arch shoulder point at one end serves as an original point, and a coordinate system is established; according to site land conditions, selecting an arch axis type and a calculation model thereof, and obtaining the rise of the arch; based on the wall back load, the arch internal force is analyzed, the height of the wall body is divided at equal height in the vertical direction, and the load of the wall body at any height is calculated; on the basis of the load of the corresponding wall height, internal force at the corresponding span representative point is calculated, the minimum thickness of the span representative point is calculated and determined according to the planned material strength, and therefore the design structure of the arched retaining wall is determined. By the adoption of the arched retaining wall, the compressive strength of masonry materials can be fully utilized, the defects that a straight wall is large in bending moment and poor in bending resistance are overcome, the height limit of an existing masonry retaining wall is broken through, and meanwhile the masonry amount is reduced.
本发明公开了一种拱形挡墙的设计方法，包括以下步骤：根据现场地形条件，选定拱形挡墙类型；采用三铰拱模型，并在两端拱肩和拱脚处设置约束，以其中一端的拱肩点作为原点，建立坐标系；根据现场用地条件，选定拱轴线类型及其计算模型，并得到拱的矢高；基于墙背荷载，对拱内力进行分析，并在竖直方向上等高度划分墙体高度，计算墙体任一高度的荷载；基于对应墙体高度的荷载，计算对应跨度代表点处的内力，并根据拟订的材料强度计算确定该跨度代表点的最小厚度，以此确定拱形挡墙的设计结构。采用本发明设计的拱形挡墙，可充分利用圬工材料的抗压强度，克服平直型墙体弯矩大、抗弯能力差的弱点，突破了现有圬工挡墙高度极限，同时降低圬工量。
