Announcement of the Ministry of Housing and Urban-Rural
Development on Publishing the National Standard of "Technical Code for
Building Slope Engineering"
"Technical Code for Building Slope Engineering" has been approved as a national
standard with a serial number of GB 50330-2013, which will be implemented on June 1, 2014.
Articles 3.1.3, 3.3.6, 18.4.1 and 19.1.1 of the code are compulsory and must be enforced
strictly. The original "Technical Code for Building Slope Engineering" (GB 50330 -2002)
shall be abolished simultaneously.
Authorized by the Research Institute of Standards and Norms (RISN) of MHURD, this
code is published and distributed by China Architecture and Building Press.

Foreword
According to the requirements of the document "Notice on Printing and Publishing
'Development and Revision Plan of Building Construction Standards and Specifications in
2007 (first batch)'" (Jian Biao [2007] No. 125) issued by the former Ministry of Construction,
the former "Unified Acceptance Standard for Building Construction Quality" (GB
50330-2002) is revised by the drafting group through extensive investigations and studies,
careful summarization of practical experience and reference to relevant national and
international standards, on the basis of widely soliciting for opinions.
The main technical contents of this code are. 1. General Provisions; 2. Terms and
Symbols; 3. Basic Requirements; 4. Geotechnical Investigation of Slope Engineering; 5.
Stability Assessment of Slope; 6. Lateral Pressure of Slope Retaining Structure; 7. Slope
Engineering for Important Construction on Slope Top; 8. Anchor; 9. Retaining Wall with
Anchor; 10. Rock Slope Retaining by Anchor-Shotcrete Retaining; 11. Gravity Retaining Wall;
12. Cantilever Retaining Wall and Counterfort Retaining Wall; 13. Pile-Sheet Retaining; 14.
Slope Ratio Method; 15. Protection and Virescence of Slope; 16. Drainage of Slope
Engineering; 17. Prevention of Engineering-triggered Landslide; 18. Construction of Slope
Engineering; and 19. Monitoring, Inspection and Quality Acceptance of Slope Engineering.
There have been some significant changes in this code in the following technical aspects.
1. The values of relevant parameters (e.g. fracture angle and equivalent angle of
internal friction) of temporary slope (including rock foundation pit slope) was specified and
the calculation of lateral pressure of temporary slope was provided;
2. With regard to the calculation related to anchor (i.e. anchor section, anchoring length
between anchoring body and stratum, and anchoring length between anchored bar and
anchoring body), the calculation method in probability limit state in the former code was
converted to safety coefficient method;
3. The assessment method for slope stability analysis was adjusted as follows. for the
stability calculation of circular sliding plane, Bishop method was recommended; and for that
of broken-line sliding plane, transfer coefficient method was recommended;
4. The calculation method for the lateral pressure of step slope was added; with regard
to seismic protection, details about the calculation of lateral pressure of slope retaining
structure were provided.
5. The rock slope retaining by anchor-shotcrete retaining for longterm slope was
partially modified and improved, and details about anchor-shotcrete retaining for temporary
6. The type of counterfort retaining wall was added and relevant technical contents
were supplemented;
7. The chapter "Pile-sheet Retaining Wall" was added and relevant technical contents
of pile-sheet retaining wall, e.g. design principle, calculations, structure and construction,
were provided;
8. The chapter "Protection and Virescence of Slope" was added and relevant technical
contents of protection and virescence of slope, e.g. design principle, calculations, structure
and construction, were provided;
9. Section 3.5 "Drainage Measures" in the former code was expanded into the chapter
drainage, design and construction method for seepage prevention;
10. Section 3.6 "Design of Slope Works with Important Construction on Top of Slope"
and Chapter 14 "Slope Deformation Control" in the former code were combined into Chapter
7 "Slope Engineering for Important Construction on Slope top" of this code, which specified
the design principle and method, correction method of lateral rock-soil pressure, specific
requirements of seismic design and safe construction for slope engineering with important
construction on slope top;
11. The prevention of engineering-triggered landslide was modified and details about
the prevention of crag and collapse were deleted;
modified and improved and the monitoring of pre-warning values for slope engineering were
provided.
The provision(s) printed in bold type is (are) compulsory one (ones) and must be
enforced strictly.
Ministry of Housing and Urban-Rural Development is in charge of the administration of
this code and the explanation of the compulsory provisions. Chongqing Architectural Design
Institute is responsible for the explanation of specific technical contents. All relevant units are
kindly requested to sum up and accumulate your experiences in actual practices during the
process of implementing this code. The relevant opinions and advices, whenever necessary,
