With the increasingly severe climate problem, countries around the world are actively taking measures to deal with climate change. China's "dual-carbon" goal is to achieve the carbon peak by 2030 and the carbon neutral by 2060, and coal-fired power plants, as an important source of energy consumption and carbon emissions, are an important part of China to achieve the dual-carbon target. Under the background of carbon peak and carbon neutrality in the power industry, coal-fired power plants will face new opportunities and challenges. This paper analyzes the energy structure, energy consumption and energy saving and emission reduction technology of China's coal-fired power plants, and puts forward relevant policy suggestions. With the proposal of China's "dual carbon" target, various regions have issued the corresponding carbon peak and carbon neutral targets to control the total carbon dioxide emissions in China. From the perspective of energy consumption, the power industry, as one of the main sources of carbon emissions, plays a vital role in achieving the "dual-carbon" goal. How to better promote the low-carbon transformation and development of the power industry is a problem to be solved.

Aiming at the problem of how to deal with a large amount of waste mud produced in the construction of expressway cast-in-place pile, this paper studies the existing waste mud treatment technology in the construction of cast-in-place pile, and proposes to adopt the pressure filtration and solidification treatment technology of urban bridge borehole abandoned slurry, and use the mud solidification and filtration equipment to separate the waste mud from mud cake and tail water. Part of the tail water is injected into the mud pond for recycling, part is reprocessed for agricultural greening and irrigation, etc. The mud cake is recycled and reused, and can be converted into backfill and green soil according to the actual needs of the site, thus solving the problems of large environmental pollution, low utilization rate of waste materials and poor civilized construction in the traditional waste mud treatment process. Finally, In view of the impact of grouting treatment on the environment of urban Bridges,a post-evaluation model of grouting treatment environment is established, which provides a scientific evaluation system for implementing the post-grouting treatment environment evaluation.

In allusion to some problems of Underground municipal  pipe network and underground utility tunnel. This thesis proposes a novel planning scheme“sun-rainshed pipe gallery”, means to combine municipal  pipe and  viaduct、overpass, form No umbrella space for us.

The reinforcement and settlement of soft soil subgrade in municipal roads have become key challenges in their overall construction. On the one hand, soft soil subgrade has the characteristics of instability and easy settlement, which brings great difficulties to the use and maintenance of roads. On the other hand, municipal road engineering construction itself has many complexities and diversities. Therefore, how to effectively reinforce soft soil roadbeds and observe settlement analysis has become an urgent problem to be solved in current municipal road construction.

This article provides a detailed exploration of the development of urban disaster risk reduction planning, the application of GIS technology in urban planning, and the current status of optimizing municipal infrastructure layout. The importance and methods of urban natural disaster risk assessment, as well as the application of GIS in urban disaster risk reduction planning, are discussed. The classification and functions of municipal infrastructure, as well as planning and design principles, are introduced. Finally, through practical case studies, the article showcases the outcomes of urban disaster risk reduction planning and municipal infrastructure layout optimization, emphasizing the significance of these methods in enhancing urban resilience, sustainability, and residents' quality of life. This article underscores the critical role of GIS technology in urban planning and management and the application of planning and management principles in achieving sustainable urban infrastructure, providing substantial support for urban development and safety.

In recent years, driven by the rapid economic development, China's urbanization process is accelerating, and the scale of urban infrastructure construction is also expanding. Although the number of construction enterprises in China is increasing, but the quality is not optimistic, many construction quality problems occur frequently, and the healthy development of the construction industry is seriously threatened. Therefore, it is particularly important to strengthen the construction quality control work. In order to further improve the effect of construction quality control, this paper mainly discusses the construction quality control as the core.
