【摘要】：地質(zhì)剖面圖是按一定的比例,用規(guī)定的符號(hào)、花紋和顏色從x,z方向揭示某地區(qū)的地層結(jié)構(gòu)與地層巖性特征的圖件,能夠直觀地表達(dá)地層的結(jié)構(gòu)和沉積規(guī)律。第四紀(jì)地質(zhì)剖面圖主要用于表達(dá)第四紀(jì)地層的時(shí)代、成因、巖性、產(chǎn)狀和構(gòu)造等方面的特性。 已有的剖面圖繪制系統(tǒng)的實(shí)現(xiàn)方法是基于桌面應(yīng)用方式,系統(tǒng)的應(yīng)用和推廣受桌面應(yīng)用方式的限制,不利于第四紀(jì)地質(zhì)鉆孔數(shù)據(jù)和剖面圖繪制系統(tǒng)在Web上的廣泛應(yīng)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(jì)地質(zhì)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(jī)性,瀏覽器上調(diào)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(wù)模式的第四紀(jì)地質(zhì)剖面圖自動(dòng)繪制方法,對(duì)剖面的繪制效率進(jìn)行改進(jìn),實(shí)現(xiàn)第四紀(jì)地質(zhì)剖面圖在Web上的自動(dòng)繪制。本文主要的研究?jī)?nèi)容與結(jié)論包括： (1)第四紀(jì)地質(zhì)剖面自動(dòng)繪制的知識(shí)與規(guī)則研究。通過(guò)對(duì)第四紀(jì)地質(zhì)剖面圖的組成要素與繪制原則、對(duì)第四紀(jì)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(jì)地質(zhì)剖面自動(dòng)繪制的知識(shí)與規(guī)則。 (2)第四紀(jì)地質(zhì)剖面自動(dòng)繪制的功能服務(wù)的構(gòu)建方法研究。對(duì)剖面自動(dòng)繪制的功能服務(wù)在服務(wù)端進(jìn)行劃分,根據(jù)知識(shí)規(guī)則具體研究各項(xiàng)服務(wù)的構(gòu)建方法和實(shí)現(xiàn)步驟,并提出有序的地層結(jié)構(gòu)類型識(shí)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?fù)潢P(guān)系構(gòu)建算法與改進(jìn)的多邊形生成算法。 (3)第四紀(jì)地質(zhì)剖面圖在瀏覽器端的自動(dòng)繪制方法研究。分析研究第四紀(jì)地質(zhì)剖面圖的服務(wù)實(shí)現(xiàn)與圖形繪制方法,以此為基礎(chǔ),根據(jù)剖面繪制的知識(shí)與規(guī)則,調(diào)用服務(wù)端的功能服務(wù),分析研究剖面圖的繪制方法,實(shí)現(xiàn)第四紀(jì)地質(zhì)剖面圖在瀏覽器端的自動(dòng)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.
