摘要 研究目的: 西部艰险山区受地形、气候及复杂地质情况的影响,制约了铁路勘察精度,以往的研究仅仅是天空地技术的简单组合,对于方法的综合应用论述不够,本研究基于西部山区铁路勘察的关键问题与实际需求,提出融合地质体时空演化过程识别的四维勘察体系,旨在为西部山区铁路勘察领域的科学研究和勘察工作提供参考。
研究结论: (1)构建了一套“天空地井”的四维勘察体系,将传统的现状勘察提升为地质体灾变演化勘察;(2)详细阐述了不同地质问题下“天空地井”技术组合原则;(3)采用“天空地井”融合勘察技术将大大提高西部山区岩性、构造、地质灾害、深部地质特征的勘察精度,该技术可广泛应用于复杂艰险山区铁路勘察中。

Abstract：Research purposes: The accuracy of railway survey is restricted by the influence of terrain, climate and complex geological conditions in difficult and dangerous mountainous areas in the western China. The previous research is only a simple combination of sky and earth technology, and the comprehensive application of the method is not discussed enough. Based on the key problems and actual needs of railway survey in western mountainous areas, this research puts forward a four-dimensional survey system integrating the identification of geological body's temporal and spatial evolution process, to provide reference for scientific research and survey work in the field of railway survey in western mountainous areas.
Research conclusions: (1) A set of four-dimensional survey system of "space-sky-ground-well" is constructed, which promotes the traditional current survey to the survey of geological body catastrophe evolution. (2) The technical combination principle of "space-sky-ground-well" under different geological problems is described in detail. (3) The "space-sky-ground-well" integrated survey technology will greatly improve the survey accuracy of lithology, structure, geological hazards and deep geological characteristics in western mountainous areas. This technology will be widely used in railway survey in complex and dangerous mountainous areas.

Key words： difficult mountainous areas space-sky-ground-well four-dimensional investigation system
