切沟形成初期 ,对公路并不形成破坏或威胁 ,但若置之不理 ,随着其不断发展扩大 ,会给公路带来致命的水毁破坏。因此 ,为防患于未然 ,一方面 ,要摸清切沟的产生与发展规律 ,以确定合适的治理措施 ;另一方面 ,为做到眼前效果与长期效果兼顾 ,应将工程措施与生物措施结合使用 ,方能做到既治标又治本。 The initial formation of the gully does not cause any damage or threat to the highway. However, if it is ignored, it will cause fatal water damage to the highway as it continues to expand and develop. Therefore, in order to take preventive measures, on the one hand, it is necessary to find out the law of the occurrence and development of cutting ditches in order to determine appropriate measures for governance; and on the other hand, in order to achieve both immediate and long-term results, engineering measures and biological measures Combination of use, in order to achieve both temporary and permanent cure.
