摘要
根据南宁,柳州两市工程地质编图实践,讨论了城市编图工作中有关编图指导思想、图件精度、地貌研究及岩土的平面三维表示方法等问题。认为城市工程地质编图直接服务于城市建设,应紧密结合城市规划要求,客观地反映城市工程地质环境质量及岩土工程的要点及特征。城市工程地质研究程度的不均一性,使编绘的同一图件存在研究程度、精度不一的问题,如何区分出这些地段以及三维反映地基土特征,直接关系到编制图件的科学性、针对性、实用性和艺术性。
This paper discusses the guiding ideology and precision of mapping, study of geornorphology and method of three-dimensional express of rock and soil in plane according to the mapping practice in Nanning and Liuzhou. It is considered that mapping must directly serve city construction and objectively reflect urban engineering geological environment and geotechnogical feature linking with city programme. The inhomogeneity of urban engineering geological study lead difference of study level and precision in a same map. To delimit these sections of an area and to reflect soil feature with three dimensions will directly effect the scientific significance, purpose, practicability and artistry.
