【摘要】：地质剖面图是按一定的比例,用规定的符号、花纹和颜色从x,z方向揭示某地区的地层结构与地层岩性特征的图件,能够直观地表达地层的结构和沉积规律。第四纪地质剖面图主要用于表达第四纪地层的时代、成因、岩性、产状和构造等方面的特性。已有的剖面图绘制系统的实现方法是基于桌面应用方式,系统的应用和推广受桌面应用方式的限制,不利于第四纪地质钻孔数据和剖面图绘制系统在Web上的广泛应用。而且,桌面绘制方法采用的地层多边形生成算法存在一定的低效性,不能满足第四纪地质剖面图在浏览器上快速绘制的的要求。由于钻孔选择具有随机性,浏览器上调用图片的方法不适用于剖面图的快速生成。因此本文提出基于服务模式的第四纪地质剖面图自动绘制方法,对剖面的绘制效率进行改进,实现第四纪地质剖面图在Web上的自动绘制。本文主要的研究内容与结论包括： (1)第四纪地质剖面自动绘制的知识与规则研究。通过对第四纪地质剖面图的组成要素与绘制原则、对第四纪地层的划分方法、地层空间分布类型以及地层尖灭规则的分析研究,制定了第四纪地质剖面自动绘制的知识与规则。 (2)第四纪地质剖面自动绘制的功能服务的构建方法研究。对剖面自动绘制的功能服务在服务端进行划分,根据知识规则具体研究各项服务的构建方法和实现步骤,并提出有序的地层结构类型识别方法、基于张力样条函数的地层线平滑算法、基于类方位角的弧段拓扑关系构建算法与改进的多边形生成算法。 (3)第四纪地质剖面图在浏览器端的自动绘制方法研究。分析研究第四纪地质剖面图的服务实现与图形绘制方法,以此为基础,根据剖面绘制的知识与规则,调用服务端的功能服务,分析研究剖面图的绘制方法,实现第四纪地质剖面图在浏览器端的自动绘制。
[Abstract]:The geological section map is a map that reveals the stratigraphic structure and lithologic characteristics of a certain area from the direction of XZ with the prescribed symbols, patterns and colors according to a certain proportion, which can directly express the formation structure and sedimentary law. The Quaternary geological profile is mainly used to express the characteristics of the Quaternary strata in terms of age, origin, lithology, occurrence and structure. The existing implementation method of section drawing system is based on desktop application mode. The application and popularization of the system is limited by desktop application mode, which is not conducive to the extensive application of Quaternary geological borehole data and profile drawing system in Web. Moreover, the formation polygon generation algorithm used in tabletop rendering method has some inefficiency, which can not meet the requirements of fast rendering of Quaternary geological profiles on the browser. Because of the randomness of borehole selection, the method of calling pictures on browser is not suitable for the quick generation of profiles. Therefore, this paper presents an automatic drawing method of Quaternary geological profile based on service mode, which improves the efficiency of section rendering and realizes the automatic drawing of Quaternary geological profile on Web. The main contents and conclusions of this paper are as follows: 1) knowledge and rules of automatic drawing of Quaternary geological profiles. Based on the analysis of the elements and drawing principles of the Quaternary geological profile map, the classification method of the Quaternary strata, the spatial distribution types of the strata and the rules of formation pinching, the knowledge and rules for the automatic drawing of the Quaternary geological profiles are established. 2) study on the construction of functional services for automatic drawing of Quaternary geological profiles. The functional services of automatic profiling are divided in the service side. According to the rules of knowledge, the construction method and realization steps of each service are studied, and an orderly recognition method of stratigraphic structure type is put forward. The formation line smoothing algorithm based on tension spline function, the algorithm of constructing topological relation of arc segment based on azimuth angle and the improved polygon generation algorithm. 3) automatic drawing method of Quaternary geological profile in browser. The service realization and drawing method of Quaternary geological profile map are analyzed and studied. Based on this, according to the knowledge and rules of section drawing, the function service of service end is called, and the drawing method of section map is analyzed. The Quaternary geological profile can be automatically drawn in the browser.
