Method and system for determining critical height of reinforced soil retaining wall
The invention relates to a method and system for determining the critical height of a reinforced soil retaining wall. The method comprises the following steps: determining an actual rotation damaged soil body area of the reinforced soil retaining wall according to a logarithmic spiral surface; performing regular image division on the actual rotation destroyed soil body area, and then determining the external power made by the soil weight of the actual rotation destroyed soil body area by adopting a superposition method according to the power made by the soil weight of the logarithmic spiral area; determining the energy consumption rate of the rib material along the whole logarithmic spiral surface according to the parameters of the rib material in the reinforced earth retaining wall; according to the soil cohesion in the reinforced soil retaining wall, the energy consumption rate generated by the soil cohesion along the whole logarithmic helicoid is determined; according to the friction coefficient between the soil body and the rib material, determining the friction energy loss rate between the soil body and the rib material along the fracture surface by adopting a splitting method; and determining the critical height of the reinforced soil retaining wall by adopting a limit analysis method according to the determined data. The method can solve the problem that the research result of the critical height of the reinforced retaining wall is not matched with the engineering practice.
本发明涉及一种加筋土挡墙临界高度的确定方法及系统。该方法包括根据对数螺旋面确定加筋土挡墙实际转动破坏土体区域；并对实际转动破坏土体区域进行规则图像划分，之后根据对数螺线区土重所作的功率，采用叠加法，确定实际转动破坏土体区域土重所作的外功率；根据加筋土挡墙中筋材的参数确定筋材沿着整个对数螺旋面的能量消耗率；根据加筋土挡墙中土体粘聚力确定土体粘聚力沿着整个对数螺旋面产生的能量消耗率；根据土体与筋材之间的摩擦系数，采用条分法，确定土‑筋之间沿破裂面的摩擦能量损耗率；根据上述确定的数据，采用极限分析法确定加筋土挡墙临界高度。本发明能解决加筋土挡墙临界高度研究结果和工程实际不相吻合的问题。
