我国西北地区地质构造运动活跃,环境脆弱,崩塌等自然灾害频发。西北地区高速公路建设不仅工程艰巨,需要大量投资,而且由于地形、地质复杂,面临许多工程地质问题,如山坡滑坍、崩塌等病害。文章结合西北地区暨甘肃省实际,就目前边坡工程出现的问题,阐述了公路边坡防护要紧紧抓住设计对象的土质、水文、气候等特点,灵活采用不同的防护型式,确保公路边坡稳定、安全、环保。
Northwest China’s active tectonic movement, the environment is fragile, collapsing and other natural disasters. The construction of the expressway in the northwest region is not only arduous and requires a large investment, but also faces many engineering geological problems due to topography and complex geology, such as slump and collapse of slopes. Based on the actual situation in Northwest China and Gansu Province, this paper elaborates on the problems of slope engineering at present. It elaborates that the slope protection of highway should grasp the characteristics of soil, hydrology and climate of the design object flexibly and adopt different protection modes flexibly to ensure the highway slope Stable, safe and environmental protection.
