Analysis on the Causes for Sliding of Support Seat of the Belt Veranda in a Concentrator Stockpile

对某矿精矿堆场皮带廊支座滑落原因进行了分析 ,建立了桩基础位移的刚性模型。模型计算结果与实测结果的对比分析 ,说明应考虑水对场地土的不利影响 ,以及大面积堆载对桩基位移的影响 ,提出宜采用群桩方案进行设计 ,并应根据桩承受的水平载荷计算其配筋。

This paper analyzes the causes leading to the sliding of the support seat of the belt veranda in a concentrator stockpile field. A rigid model is established for the pile foundation. Comparison of the model-based calculation results with field test results indicates that consideration must be given to the adverse influence of the run-off water on the stockpile field as well as to the adverse influence of large scale heaping and loading on the displacement of the pile foundation. It is proposed that cluster piles should be designed and reinforcement should be considered based on the horizontal loading of the piles.
