锚杆格梁加固既有挡土墙的计算

Study on the Calculation Method of Existing Retaining Wall with Anchor Pile Gride Beam

以目前广泛存在的既有重力式挡土墙为研究对象,研究对其采用锚杆格梁方式进行加固的计算方法.通过计算表明:如考虑原挡土墙的承载能力则会得到较高的安全系数,而不考虑原挡土墙的承载能力则会得到较低的安全系数.因此,建议在进行加固设计计算时要充分调查原挡土墙的破坏情况,以便采取相应的加固措施.

According to the widely Existing retaining wall, this paper studies the calculation method of existing retaining wall reinforced by anchor pile grid beam. The results,by means of through calculation, reveal that a higher factor of safety is got if considering the capacity of the original retaining wall, yet regardless of the carrying capacity of the original retaining wall, a lower safety factor is gained. Therefore, in order to take appropriate reinforcement measures, the paper points out that attention must be paid to the fully investigation of the destruction of the original retaining wall during the reinforcement design calculations.
