委内瑞拉北部高速铁路工程地质特征分析

委内瑞拉北部铁路Tinaco—Anaco段，是中国中铁承建的工程总承包(EPC)合同工程，铁路全长465km，设计时速客车220km/h，货车120km/h，是中国高速铁路建设走向世界的重要工程。针对该铁路工程地质条件进行了研究，从地层岩性、地质构造、水文地质条件等方面阐述了该铁路沿线的工程地质特征，总体地质条件较好，同时也分析了工程建设中存在的主要工程地质问题，并提出了建议。

Analysis on Engineering Geological Characteristics of Northern Venezuela High-speed Railway

Northern Venezuela Railway Tinaco--Anaco Section is the general contracting project for engineering, procurement and construction （EPC） undertaken by China Railway. The railway has the total length of 465 km and the design speed of 220 km/h for passenger train and 120 km/h for freight train, which is the important project for China＇s high-speed railway construction to the world. In this paper, through analyzing the geological conditions of this railway, the engineering geological characteristics along the railway line are described from the aspects of formation lithology, geological structure and hydrogeological condition. The results showed that the overall geological conditions are good. At the same time, the existing main geological problems during construction are analyzed and the countermeasures are put forward.
