摘　　要：工程地质评价不仅仅是隧道工程设计和施工的基础,也能够为隧道设计提供反馈信息,为施工提供指导。为深入研究隧道工程的地质评价,降低发生安全事故的风险性,以广东省龙怀高速公路马口排岩溶隧道为工程背景,通过实际现场地质勘察的方法,基于马口排隧道工程地质条件,对马口排隧道涌水量进行预测,从隧道进口、出口、洞身等方面对马口排隧道的工程地质状况进行了分段评价,以为类似岩溶隧道的工程地质评价具有一定借鉴。Engineering geological evaluation is not only the foundation of tunnel engineering design and construction, but also can provide feedback information for tunnel design and provide guidance for construction. For the in-depth study of tunnel engineering geological evaluation, reduce the risk of accidents, taking Guangdong province expressway Longhuai karst tunnel of Makoupai as the engineering background, through the method of geological survey of the actual scene, the engineering geological conditions of tunnel based on the prediction of tin row, row of tin water inflow in the tunnel, the tunnel hole body, import and export other aspects of the evaluation of the engineering geological conditions of a block row tunnel. It can be used for reference to other similar karst tunnel engineering geological evaluation.
