摘要
滑坡、崩塌、岩溶、膨胀土是影响广西地区公路工程建设的主要地质灾害,文章在全面调查广西地貌,自然环境特征的基础上,系统研究了该区地质灾害特点、分布及对公路工程的危害;针对以往公路自然区划中对气候(水热)因素考虑较多的情况,依据《公路自然区划标准》三级区划的第一种方法,遵循公路自然区划原则,借鉴自然区划方法,利用计算机平台(GIS),制定广西公路三级地貌区划体系,该体系对广西地区的公路工程建设具有较大使用价值;依据该区划方案提出预防和治理该区主要公路地质灾害的措施。
Landslides, collapse, karst highway engineering construction in environment features of Guangxi and expansive soil are the main geological disasters that have a great impact on Guangxi region, based on comprehensive investigation in physiognomy, natural , the paper systematically studies the geological disasters' characteristic, distribution and the hazards for highway engineering; Aiming at the past highway natural regionalization which more considered climatic factors(water and hot), according to the first method of the "Standard of Climatic Zoning for Highway" third regionalization, following the principle of highway natural regionalization, from natural regionalization methods, using computer platform (GIS), making the third physiognomic regionalization system for highway in Guangxi, the system have great value for highway engineering construction in Guangxi region; based on the regionalization scheme, putting forward measures to prevent and control major highway geological disasters in the region.
