摘要
从支承压力的形成机理入手,通过对支承压力形成的五个阶段进行分析,创新地提出综合移动角起于支承压力边缘的方案,建立了相关的结构力学模型和求解方程。通过该方案在实测中的验证表明,该方案具有较强的适应性和稳定性,解决了传统算法中同一地层下综合移动角差别较大的问题。
Starting from the mechanism of abutment pressure formation, this paper analyzes the five periodsof abutment pressure development and innovatively proposes a new scheme in which the synthetic angle ofdraw starts with the marginal of abutment pressure. This paper sets up the structural mechanics model andsolution equations. The practical measures show that this scheme has stronger adaptability and stability andthis algorithm can solve the problem of larger deviation of synthetic angle of draw calculated by the traditional algorithm in the same stratum.
