【摘要】：地質剖面圖是按一定的比例,用規(guī)定的符號、花紋和顏色從x,z方向揭示某地區(qū)的地層結構與地層巖性特征的圖件,能夠直觀地表達地層的結構和沉積規(guī)律。第四紀地質剖面圖主要用于表達第四紀地層的時代、成因、巖性、產(chǎn)狀和構造等方面的特性。 已有的剖面圖繪制系統(tǒng)的實現(xiàn)方法是基于桌面應用方式,系統(tǒng)的應用和推廣受桌面應用方式的限制,不利于第四紀地質鉆孔數(shù)據(jù)和剖面圖繪制系統(tǒng)在Web上的廣泛應用。而且,桌面繪制方法采用的地層多邊形生成算法存在一定的低效性,不能滿足第四紀地質剖面圖在瀏覽器上快速繪制的的要求。由于鉆孔選擇具有隨機性,瀏覽器上調用圖片的方法不適用于剖面圖的快速生成。 因此本文提出基于服務模式的第四紀地質剖面圖自動繪制方法,對剖面的繪制效率進行改進,實現(xiàn)第四紀地質剖面圖在Web上的自動繪制。本文主要的研究內容與結論包括： (1)第四紀地質剖面自動繪制的知識與規(guī)則研究。通過對第四紀地質剖面圖的組成要素與繪制原則、對第四紀地層的劃分方法、地層空間分布類型以及地層尖滅規(guī)則的分析研究,制定了第四紀地質剖面自動繪制的知識與規(guī)則。 (2)第四紀地質剖面自動繪制的功能服務的構建方法研究。對剖面自動繪制的功能服務在服務端進行劃分,根據(jù)知識規(guī)則具體研究各項服務的構建方法和實現(xiàn)步驟,并提出有序的地層結構類型識別方法、基于張力樣條函數(shù)的地層線平滑算法、基于類方位角的弧段拓撲關系構建算法與改進的多邊形生成算法。 (3)第四紀地質剖面圖在瀏覽器端的自動繪制方法研究。分析研究第四紀地質剖面圖的服務實現(xiàn)與圖形繪制方法,以此為基礎,根據(jù)剖面繪制的知識與規(guī)則,調用服務端的功能服務,分析研究剖面圖的繪制方法,實現(xiàn)第四紀地質剖面圖在瀏覽器端的自動繪制。
[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.
