摘要
随着我国城市道路网的逐渐饱和,西部偏远地区道路的发展迫在眉睫。尤其我国贵州、云南、四川等地区,公路建设地质条件复杂多样,具有典型的山区地形陡峻、不良地质的特点,这些区域公路工程的地质勘察、不良地质调查及治理尤为重要。文章通过分析高速公路前期地质勘察现状,结合各国家级、省级高速公路地质勘察案例,详细论述了各种不良地质对高速公路建设的影响及方案比选建议。研究表明,对于不可治理的特大不良地质体,前期可通过灾害普查提前绕避;对于规模较小的不良地质体,可通过支挡防护工程进行及时治理。
With the gradual saturation of urban road network in China,the development of roads in remote western regions is imminent.Especially in Guizhou,Yunnan,Sichuan and other regions,the geological conditions of highway construction are complex and diverse,with the typical characteristics of steep terrain and unfavorable geology in mountainous areas.The geological survey,unfavorable geological survey and treatment of highway engineering in these regions are particularly important.Based on the analysis of the current situation of early geological survey of highways,combined with the geological survey cases of national and provincial highways,this paper discusses in detail the influence of various unfavorable geology on highway construction.The study shows that for unmanageable extra-large unfavorable geological bodies,it can be avoided in advance through disaster census in the early stage;and for small-scale unfavorable geological bodies,it can be timely treated through support protection projects.
