摘要
喀斯特地区修建高速公路选线是关键。线路的合理性需要从不同角度,利用目标综合分析,协调设计。文章以多目标协调设计为原则,公路功能为主线,地质、生态选线优先,灵活运用技术指标,平衡处理及高速公路建设安全、经济、美观、舒适的关系。这些技术应用在河池至都安高速公路选线中,使其成为广西首条喀斯特地区典型示范工程。
The route selection is the key for expressway construct in karst area.The rationality, of the route needs the comprehensive analysis from different angles and by using the target, with coordinated design.This article takes the multi-objective coordinated design as the principle,with the highway function as the main line,the geology and ecology route selection as the priority,and through the flexible use of technical indexes, the balan.ced treatment was conducted regarding the relationship among expressway construction safety, economy, beauty and comfort.These technologies were used in Hechi-Du＇an Expressway route selection, making it the first demonstration project in karst area in Guangxi.
