城市地质环境的工程地质分析与图系编绘

城市建设与地质环境密切相关,城市大比例尺工程地质编图是对城市地质环境进行工程地质分析的结果。在阐述城市地质环境的特征及城市建设作用对地质环境施加的改造作用之基础上,提出城市工程地质研究的3个命题:建立第四系地层组合模型,区域地壳稳定性及地下水运移与贮存状态。结合具体城市特有的自然因素讨论工程地质问题是城市工程地质分析的要点。指出编图精度同时取决于资料丰富程度及分析的准确度。

ENGINEERING GEOLOGICAL ANALYSIS AND MAPPING IN THE URBAN DISTRICT

Urban construction is related to the geological environment, the large scale maps of engineering geology in the urban district is the result of engineering geological analysis for the geological environment. After expounding the characteristic of the environment and some actions for urban construction to the environment, the three proposals of urban engineering geological analysis which including to construct the strata model about Quatrenary system, to study the stability of tectonic element and to analyse the moving and storage state of underground water, have been offered. The author of this paper pointed out that the mapping precision is controlled by data number and analysis accuracy.
