第四纪地质的研究是水文地质工程地质的重要基础工作.一些大的第四纪沉积盆地、第四纪沉积物的分布和结构、新构造运动的性质等,决定着水文地质条件及其变化规律.第四纪沉积物的形成及形成后的表生地质作用,对沉积物的岩性、结构、物理—力学性质等一系列工程地质特性有着重要影响.现代物理地质现象的发生发展,是以区域的第四纪古地质环境为背景的.第四纪地质研究对水文地质工程地质工作的意义愈加深远.
The study of quaternary geology is an important basic work of hydrogeological engineering geology.A large Quaternary sedimentary basin, the distribution and structure of Quaternary sediments, the nature of neotectonic movement determine the hydrogeological conditions and their changes The formation of Quaternary sediments and the epigenetic geological effects after their formation have an important influence on a series of engineering geological characteristics such as lithology, structure, physical-mechanical properties of sediments, etc. The occurrence and development of modern physical geology phenomena are With Quaternary paleoenvironment of the region as the background.The study of Quaternary Geology has far-reaching significance to hydrogeological engineering geological work.
