Comparison of the development of engineering geological investigation codesbetween water conservancy and railway, highway industries

Abstract

In order to explore the similarities and differences in the development of engineering geological investigation codes in the water conservancy and railway, highway industries since the 1st Five-Year Plan until now, a comparative analysis method is used to analyze and compare from five aspects: development mode and scope of application, existing projects, unfavorable geological condition, and provisions for ancillary construction projects. The results show that:(1) The engineering geological investigation codes in the water conservancy industry has developed in a dispersed manner, while in the railway and highway industries, it has developed in a convergent manner, with different development ways;(2) The scope of application of the Code for Engineering Geological Investigation of Water Resources and Hydropower is gradually narrowing for medium-sized projects, while the Code for Geology Investigation of Railway(Highway) Engineering is gradually expanding in terms of applicable types(grades), and there are significant differences in the provisions of the scope of application;(3) The water conservancy regulations implemented after the reform and opening up and the current highway regulations do not have investigation regulations for existing projects, while the railway codes have had corresponding provisions in place for 39 years, and there are significant differences in the provisions for existing projects;(4) The water conservancy industry codes have many shortcomings in the provisions for unfavorable geological conditions, while the railway and highway industries codes use professional terminology and have specific codes and chapters to guide investigation work, with significant differences in the provisions for unfavorable geological conditions;(5) The water conservancy industry codes implemented from 1978 to the present do not have provisions for ancillary construction projects, while the railway and highway industries codes have had corresponding provisions in place for over 20 years, and there are clear differences in the provisions for ancillary construction projects. The results indicate that some of the regulations in water conservancy standards are not as good as those in railway and highway standards, and it is necessary to develop a Code for Engineering Geological Investigation of Water Resources and Hydropower that is suitable for the high-quality development of water conservancy in the new development stage.
