THE ESTABLISHMENT OF THE MATHEMATICAL MODEL FOR DIRECTION CHANGING BROKEN LINE SECTIONS WITH A DISCUSSION OF THE CONSTRUCTION METHOD

摘要: 变方向折线剖面是在地形、地质情况较为复杂地区普遍采用的实测地质剖面方法。其地质剖面图目前一般用几何作图方法以投影法成图。这种方法成图过程繁琐，误差大，存在一系列问题。笔者提出了一套准确的坐标法计算方法及与其相适应的展点作图方法；对传统的岩层厚度计算方法进行了革新，提出了一个非判别选择的通用公式；对完善地质剖面图的编制方法进行了讨论

Abstract: The construction of the direction changing section is a method of measuring a geological section applied commonly in areas with complex topographic and geological condition.The geological section is generally constructed using the geometric construction method and projection method.The construction process is overlaborate with a big error.In the paper the author proposes an accurate calculation method by use of coordinates and its related expanded point constrction method,makes and innovation of the conventioned calculation of the thickness of strata and puts forward a universal formula of non deterministric selection.Besides ,he also discusses how to perfect the method of constructing a geological section.
