DZ/T 0219-2006Specification of design and construction for landslide stabilization (English PDF)

Foreword

Appendix A, Appendix B, and Appendix C of this specification are normative appendices.

This specification was proposed by the Department of Geology and Environment of the Ministry of Land and Resources.

This specification is under the centralized management of the Department of International Cooperation and Science and Technology of the Ministry of Land and Resources.

The main drafting unit of this code. China Geological Survey.

Introduction

In order to improve the technical level of landslide prevention and control, unify technical standards, ensure sufficient geological basis, safety and reliability, economical and reasonable, technically feasible, and specially made Make this specification.

This code is compiled on the basis of full study of domestic and foreign technical standards for landslide prevention and control and more mature methods and technologies.

Various methods have fully solicited the opinions of relevant units and experts across the country, and the resettlement and construction of the Three Gorges Project reservoir area, as well as other municipal and engineering construction Design, the natural geological landscape protection landslide prevention project was tried out and repeatedly revised and improved, and the final draft was reviewed and finalized.

This code covers the feasibility plan design, preliminary design and construction drawing design of landslide prevention and control projects, as well as the design of emergency treatment projects Provisions and regulations on drainage, anti-slide piles, prestressed anchor cables, lattice anchoring, gravity retaining walls, grouting reinforcement, brushing for load reduction, backfill Technical methods such as foot and plant protection, as well as construction technical methods put forward requirements.
