Introduction

1. Background and significance of standard formulation

With the acceleration of urbanization and the increasing tension of land resources, the development and utilization of underground space has become an important direction for the development of modern cities. The "Classification of Urban Underground Space and Underground Engineering" (GB/T41925-2022) standard came into being, aiming to regulate the development and utilization of urban underground space and ensure that it serves urban construction and management in a scientific and reasonable manner.

2. Comparative analysis of standard frameworks

Classification dimensions	Specific classification	Scope of application
Functional characteristics	Transportation, municipal utilities, social public services, etc.	Applicable to the planning and design of underground space within the city
Construction form	Single-building, combined-building, regional integrated, etc.	Guide the construction and management of underground projects
Development depth	Shallow, sub-shallow, deep, ultra-deep, etc.	Influence on the structural design and construction technology of underground space

3. Recommendations for Standard Implementation

Case Study: In a certain urban rail transit project, the underground space classification and engineering design were carried out according to the GB/T41925-2022 standard. The type of underground transportation space was determined through functional characteristics analysis, and the appropriate construction method (such as shield method or pipe jacking method) was selected in combination with the geotechnical environment. This standardized implementation method effectively improves the scientificity and operability of the project.
