摘　　要：许多公路两侧都存在高陡路堑边坡,由于夏季雨水充沛,在降雨影响下,高边坡时常会发生崩塌。因此,对公路两侧高边坡防护措施及稳定性进行分析。以利川市谋道镇龙水村九组318国道回头弯K0+010~K0+070左侧路堑高边坡为例,在夏季暴雨影响下,该边坡发生崩塌。文章分析该边坡发生崩塌的主要诱发因素,并提出治理防护措施,通过有限元软件建立仿真模型分析其稳定性,以此验证防护措施的合理性。There are high and steep cut slopes on both sides of some highways.Due to abundant rainfall in summer,high slopes often collapse under the influence of rainfall.Therefore,the protective measures and stability of high slopes on both sides of the highways are analyzed.Taking the high cut slope at the left side of K0+010~K0+070 of the return bend of 318 national highway in Group 9,Longshui Village,Moudao Town,Lichuan City as an example,the slope collapses under the influence of rainstorm in summer.The main triggering factors for the slope collapse are analyzed,and the control and protective measures are put forward.The simulation model is established by using the finite element software to analyze its stability,so as to verify the rationality of the protective measures.
