Tiêu chuẩn quốc gia TCVN 14393:2025

TCVN 14393:2025 establishes essential design requirements for construction in challenging geological environments, specifically mining areas and areas with collapsible soils. The development of this national standard is critical for ensuring the safety, stability, and long-term functionality of buildings and structures subjected to ground deformation and subsidence. It addresses the unique engineering complexities arising from mining activities and the inherent instability of certain soil types. By providing clear technical guidelines, this standard aims to minimize risks, protect human life, and safeguard infrastructure assets in these high-risk zones, setting a crucial framework for resilient construction practices in Vietnam.

The Vietnamese National Standard TCVN 14393:2025 provides a comprehensive framework for the design requirements of buildings and structures situated in mining areas and on collapsible soils. This document is crucial for addressing the significant challenges posed by ground deformation and subsidence in such hazardous environments. The standard outlines general provisions, starting with the scope of application, excluding seismic zones and specific infrastructure like roads or airports, and details a robust list of referenced documents, including various TCVNs related to soil testing and construction. Key to its approach are numerous definitions that clarify concepts like initial slumping pressure, relative curvature radius, vertical deformations of land surface, and area of undermining influence, providing a precise technical vocabulary for practitioners. The standard specifies general requirements covering urban planning, structural protection solutions, methods to reduce uneven settlement, and continuous monitoring during construction and operation. It also delves into design principles, emphasizing the need for comprehensive geological surveys and the consideration of diverse ground deformation types. Designers are guided on selecting appropriate structural systems—rigid, flexible, or combined—and applying relevant safety and working condition factors. This meticulous approach ensures the construction of resilient infrastructure, minimizing risks, and promoting sustainable development in regions impacted by mining activities or unstable collapsible soils, thereby safeguarding both human well-being and economic investments.
