Title: Report of the Next Generation of Civil Engineering
Abstract: The development of civil engineering technology is a major issue related to the national economy and people's livelihood, especially in the modern era where new technologies are emerging in all walks of life. Combining with the current development status of civil engineering technology in the world today, the author combed the new technologies closely related to the development of civil engineering technology in recent years. These new technologies mainly include: assembly structure, intelligent manufacturing, 3D printing, and industrial digitization. The existing high-tech and civil engineering technology developments are introduced. Based on the current domestic and foreign technological development environment, the author puts forward the development forecast of the next generation of civil engineering technology and the company's countermeasures. These predictions and suggestions are of great significance for the national government to formulate policies or the guidance for modern enterprises to formulate development strategies.

Title: Study on Evaluation Technology of Regional Grouting Treatment Effectiveness to Limestone Aquifer of Coal Seam Floor in North China Type Coalfields Based on Two-Roadways Parallel Electrical Method
Abstract: In recent years, the regional grouting treatment technology for limestone aquifers of coal seam floor in North China type coalfields has been developed significantly. However, the detection and evaluation of water inrush hazards after grouting treatment for limestone aquifers has not yet formed a complete technical system. In view of the high cost and low amount of information of traditional grouting evaluation methods(such as water pressure test method, borehole television method, drilling core method, etc.), it is proposed to collect geoelectric data by two-roadways parallel electricity method, to process geoelectric data by the whole space three-dimensional resistivity inversion technology and to draw a three-dimensional resistivity distribution diagram. Combined with the geological structure, hydrogeological characteristics and grouting information of the detection area, the effect of grouting treatment in limestone aquifer of coal seam floor can be evaluated. This technology was applied to the detection and evaluation of the grouting treatment effectiveness to the L8 limestone aquifer of the 2-1 coal seam floor of the 11291 working face in Zhaogu No.1 Coal Mine, which effectively guided the safe production of the working face and achieved good practical effects.
