道路建筑材料的调查是公路勘察中的一项主要工作,它的成果不仅影响桥涵、防护、路面等工程结构物质量的优劣,而且影响工程造价。筑路材料调查的外业工作时间是短促的,往往又是在偏僻或边远地区工作,资料缺乏,尤其在兄弟民族地区,相互语言不通,如单纯地依赖于习惯上通用的挖采、询问的调查方法,难于达到以上目的,必须突破过去那种局限性的工作方法,广泛应用地质、地貌、地植物以及地物等方面的知识,综合地进行调查研究,科学地进行分析论证,才可以多快好省地完成任务。现将自己实际工作中的一些体会简介如下。一、地质凋查法:根据路线所经地区的地质构造和地质条件的特点,事先掌握好较大范围内的岩石、土壤特征,然后再逐段进行细致的调查工作,这样可以做到心中有数,工作不至被动。如在单斜构造中较陡的一面,岩石往往裸露,岩性一目了然,开采时也
The investigation of road construction materials is a major task in highway survey. Its achievements not only affect the quality of engineering structures such as bridges and culverts, protection and pavement, but also affect the construction cost. The survey of road construction materials has short working hours in the field and often works in remote or remote areas with a lack of information. In particular, in fraternal areas, mutual language barrier exists. For example, relying solely on customary mining and quarrying Investigation methods, it is difficult to achieve the above objectives, we must break through the limitations of the past that the working methods, extensive use of geology, geomorphology, plants and terrain and other aspects of knowledge, conduct a comprehensive investigation and study, scientific analysis and demonstration, can only be more Quickly and economically complete the task. Now my own experience in some of the actual work is as follows. First, the geological investigation method: According to the route through the region’s geological structure and geological conditions of the characteristics of a large area in advance to grasp the rock, soil characteristics, and then paragraph by paragraph to carry out detailed investigations, so you can be aware of Work is not passive. As steep side of the monocline structure, the rock is often exposed, lithology at a glance, when mining
