DZ/T 0262-2014Specification of landslides investigation for towns (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard was proposed by the Ministry of Land and Resources of the People's Republic of China.

This standard is under the jurisdiction of the National Land Resources Standardization Technical Committee (SAC/TC93).

This standard was drafted. China Geological Environment Monitoring Institute, China Geological Survey Wuhan Geological Survey Center, China Geological Survey Bureau Xi'an Geological Survey Center, Chengdu Geological Survey Center of China Geological Survey.

Introduction

This standard is formulated for the purpose of standardizing and guiding the development of geological disasters in towns.

With the rapid development of China's social economy, the scale of construction and population of the towns has expanded rapidly, and geological disasters such as landslides, collapses and mudslides have intensified.

trend. The results of the previous geological surveys cannot fully meet the needs of geological disaster monitoring and early warning, prevention and control, and town development planning.

Real geological data, especially for survey data with larger scale and higher precision. To this end, this standard has been specially formulated to unify the geological disasters of the towns.

Check technical standards to provide sufficient, safe and reliable geological data for disaster reduction and prevention work.

This standard is divided into 12 parts, including. scope, normative references, terms and definitions, general rules, design review, regional geological environmental conditions Investigation, slope survey, hidden danger survey, technical methods, analysis and evaluation, quality inspection, data collation and results compilation.

Code for exploration of landslides and debris flows in towns

1 Scope

This standard stipulates the general rules, design review, regional geological environmental conditions survey, slope survey, hidden dangers of the landslide collapse debris flow exploration Requirements for surveys, technical methods, analysis and evaluation, quality inspection, data collation and results compilation.

This standard is applicable to the landslide, collapse and debris flow exploration of the towns in the geological disaster-prone areas.

3 Terms and definitions

The following terms and definitions apply to this document.

Market town

Most districts and township administrative centers below the county have certain commercial services, public facilities such as culture, education and health, and have corresponding hinterland support and habits.

Both are called market towns. This standard refers to the market towns in the landslide-ridden debris flow-prone area, including its built-up area and planning area.

Geological disaster geologicalhazard Unfavorable geological effects cause loss of human life and property and ecological environment. This standard mainly includes landslides, collapses, mudslides, and ground collapses.

Disasters such as subsidence, ground fissures, and ground subsidence.

Geological hazard geological hazardpotential Potential geological hazard points. Usually refers to the investigation of geological disasters through ground geological, topographic and influencing factors.
