Abstract
In this study, the theoretical basis, advantages, construction points and innovative application of concrete in underground engineering are deeply discussed. The theory of mechanical properties and durability of concrete in underground engineering is systematically analyzed, including its elastic modulus, compressive strength, tensile strength, shear strength, permeability, impermeability, carbonization and chemical corrosion. The interaction between concrete and soil is studied in detail, including bond strength, interface characteristics, ground stress and support structure design. The study also highlights the many advantages of concrete in underground engineering, such as excellent compressive performance, good durability, construction convenience and low maintenance costs. At the same time, the key points of construction were comprehensively sorted out, including the key links such as preliminary preparation, foundation construction, waterproof treatment and construction supervision. In terms of innovative application, this study focuses on the research and development and application of new materials and new technologies, advocates the environmental protection concept of low carbon emission and resource saving, and discusses the application prospect of automation, digitalization and intelligent construction technology. It also explores the development and application of multi-functional concrete such as self-healing and radiation protection, which brings new development opportunities for underground engineering. The purpose of this study is to systematically study the application of concrete in underground engineering, provide theoretical support and practical guidance for the design, construction and maintenance of underground engineering, and promote the sustainable development and innovation in the field of underground engineering.
