巴基斯坦喀喇昆仑公路典型崩塌治理方案研究

通过对改建的巴基斯坦喀喇昆仑公路沿线自然条件分析，总结出沿线崩塌地质灾害的成灾机理，并以K520，K605两处崩塌为例，经过多方案的比选，介绍典型崩塌治理方案及处治措施。为避绕崩塌，K520工点采用短隧道方案进行治理；而K605崩塌工点，则采用悬出路台方案进行治理。实践表明均取得良好效果，既能保障工程和运营安全，在经济上也是合理的。

Study on Treatment Measures for Typical Collapse of Karakoram Highway in Pakistan

Based on the analysis of the natural conditions along the proposed Karakoram Highway in Pakistan, this paper summarizes the disaster mechanism of the collapse geological hazards along the line. Taking the collapse of K520 and K605 as an example, the treatment measures of typical collapse are introduced through comparison and selection of various schemes. To avoid collapse; K520 work point adopts short tunnel scheme for treatment; K605 collapse work point adopts the cantilevered road station solution for governance. The practice shows that both of them have achieved good results, which can not only ensure the safety of engineering and operation, but also be economically reasonable.
