Ecological geogrid slope protection stability analysis method under heavy rainfall condition
The invention relates to a method for analyzing the stability of an ecological geogrid protection slope under a heavy rainfall condition. The method comprises the following steps: selecting the ecological geogrid protection slope to construct an equivalent homogeneous protection slope calculation model; applying an MQ-RBFCM model to disperse a saturated-unsaturated seepage control equation and first and second types of boundary conditions, distributing points in a computational domain and at a boundary to respectively meet the discrete control equation and the boundary conditions, establishing an algebraic equation set, calculating a steady-state seepage field in the ecological geogrid revetment when rainfall does not occur, and analyzing a free liquid level of the revetment under the condition; taking the steady-state seepage field as an initial state of transient seepage problem analysis, applying rainfall intensity, and performing transient analysis; the pore water pressure distribution condition, the safety coefficient and the change rule of the critical slip crack surface of the slope protection at each moment are calculated and used for analyzing the stability of the ecological geogrid. The method is beneficial to quickly analyzing the influence of the rainfall effect on the stability of the ecological geogrid slope protection, so that potential risks are reduced, and the stability and reliability of the slope protection are improved.
本发明涉及一种强降雨条件下生态土工格栅护坡稳定性分析方法，包括：选取生态土工格栅护坡构建等效均质的护坡计算模型；运用MQ‑RBFCM模型离散饱和‑非饱和渗流控制方程及第一、二类边界条件，在计算域内及边界处布点分别满足离散控制方程及边界条件，建立代数方程组，计算未发生降雨作用时生态土工格栅护坡内的稳态渗流场，分析该情况下护坡的自由液面；以稳态渗流场作为瞬态渗流问题分析的初始状态，施加降雨强度，进行瞬态分析；计算护坡各个时刻的孔隙水压力分布情况、安全系数及临界滑裂面的变化规律，用于分析生态土工格栅的稳定性。该方法有利于快速分析降雨作用对生态土工格栅护坡稳定性的影响，进而减少潜在风险，提高护坡的稳定性和可靠性。
