无论是新建或改建一条公路,都须先进行勘察、测量,通过对现地实际情况取得足够的资料数据,而后才能够按照目的要求标准作出设计,以达到实现这一工程的目的。所以说勘察、测量是实现某一工程的首要一环。就公路工程而言选线工作又是测量工作中的首中之首。它对一条公路测量的质量如何,水平高低起着决定性的作用。选线工作既是一项涉及到公路、桥梁、地质、水文、气象、测量、造价等诸多方面的技术工作,而又涉及到方方面面的政策问题,可以说是一项多方面的综合性技
Whether a new road or a new road is to be reconstructed, surveys and surveys must first be carried out to obtain sufficient data on the actual conditions of the area before it can be designed in accordance with the requirements of the objectives so as to achieve the objective of the project. So survey, survey is to achieve a project a primary link. In terms of highway engineering, the work of selecting lines is again the first of the first measurements in the work. It plays a decisive role in the quality of a road survey and its level. Route selection is not only a technical project involving many aspects of roads, bridges, geology, hydrology, meteorology, surveying, and cost, but also involves various aspects of policy issues. It can be said that the multi-faceted comprehensive technology
