摘要/Abstract

摘要： 广东省境内花岗岩分布广泛，风化残积土路堑边坡坡面冲刷严重．文中分析了广东省境内花岗岩风化残积土路堑边坡冲刷稳定性的影响因素，据此选定坡面冲刷稳定性模糊评价的评价因素及其隶属函数，建立合理的模糊评价模型．采用模糊评价方法对广东省英德地区典型花岗岩风化残积土路堑边坡工程实例进行坡面冲刷稳定性评价，以验证所提出的方法的有效性．结果表明：花岗岩路堑边坡未经加固处理时，坡面冲刷稳定性差；通过坡面土质改良和坡面框架植草防护后，抗冲刷稳定性显著提高；路堑边坡冲刷稳定性的模糊评价方法具有较广的适用性．

Abstract:

Granitite distributes widely in Guangdong.The surface of the cutting slope composed by the granitite weathering remaining soil is scoured seriously.In this paper,the main factors influencing the scouring stability of the cutting slope were analyzed,according to which the evaluation indexes and corresponding membership functions of the fuzzy evaluation for the scouring stability were determined,and a reasonable evaluation model was set up.The proposed method was then used to evaluate the scouring stability of a typical cutting slope example in Yingde area of Guangdong,thus verifying the effectiveness of the fuzzy evaluation.The results indicate that the scouring stability of the cutting slope is poor without reinforcement and protection,and obviously becomes better by stabili· zing the surface soil and planting vegetables between concrete grids on the slope.It is also shown that the fuzzy method to evaluate the scouring stability is of great applicability.

Key words: granitite, cutting slope, scouring stability, fuzzy evaluation
