区域地质条件是公路边坡病害发生的内在因素,而随着人类不合理经济活动的增强,生态环境遭到强烈破坏,诱发公路边坡地质病害进一步加剧。因此,在地质条件明确的前提下,规范人类经济活动,从根本上治理生态环境,从而减少公路边坡灾害。结合广东省清远~连州一级公路升级改造工程(高速化)剖析了出现公路边坡病害的影响因素。 Regional geological conditions are the internal factors of roadside slope disease, and with the unreasonable economic activities of human beings, the ecological environment has been severely damaged, which further aggravates the geological disasters on highway slope. Therefore, on the premise of clear geological conditions, regulate the economic activities of human beings and fundamentally control the ecological environment so as to reduce the side slope disasters. Combined with the upgrading and reconstruction project of Qingyuan ~ Lianzhou-class highway in Guangdong Province, the influencing factors of highway slope disease were analyzed.
