1 General Provisions
1.0.1 This code is prepared with a view to implementing the national technical and economic policies in building slope engineering investigation, design, construction and quality control so as to achieve technical advancement, safety and reliability, economy and rationality, guaranteed quality and environmental protection.
1.0.2 This code is applicable to the slope engineering of building and rock foundation pit whose rock slope is up to 30m (including) and soil slope to 15m (including) in height.
The slope engineering exceeding the above-mentioned height limits or that with complicated geological and environmental conditions shall not only comply with this code but also be specifically designed and take effective and reliable reinforcement measures.
1.0.3 The building slope engineering of soft soil, collapsible loess, tjaele, expansive soil and other special geotechnical and erosive environments shall additionally comply with the current appropriate professional standards of the nation.
1.0.4 Taking comprehensive consideration of factors such as engineering geology, hydrological geology, slope height, environmental conditions, various actions, adjacent construction, underground public utilities, construction conditions and construction period, building slope engineering shall be elaborately designed and carefully constructed as appropriate to local conditions.
1.0.5 Building slope engineering shall not only comply with this code but also the current relevant standards of the nation.
2 Terms and Symbols
2.1 Terms
2.1.1 Building slope
Artificial slope formed by excavation or filling construction of construction and municipal engineering and natural slope having adverse effects on construction safety or stability, on building site and its surrounding. It is hereinafter referred to as "slope".
2.1.2 Slope retaining
Actions, i.e. structural retaining, reinforcement and protection, taken so as to guarantee the stability and environment safety of the slope.
2.1.3 Slope environment
A general term of the rock and soil masses, water systems, constructions, roads and pipe networks within the slope-affected area or affecting the slope safety.
2.1.4 Longterm slope
Slope of a design service life above 2 years.
2.1.5 Temporary slope
Slope of a design service life up to and including 2 years.
2.1.6 Anchor (anchorage)
Member (or system) transmitting tension to stable rock-soil layer. If steel strand or high-strength steel tendon is adopted and a pre-holding stress is applied, it is then termed as anchorage.
2.1.7 Retaining wall with anchors
Retaining structure composed of anchor (anchorage), pile and plate facing.
2.1.8 Anchor-shotcrete retaining
Retaining structure composed of anchored bar and shotcrete facing.
2.1.9 Gravity retaining wall
Retaining structure keep slope stabilized by its own gravity.
2.1.10 Counterfort retaining wall
Retaining structure composed of vertical plate, base plate, counterfort and back fill.
2.1.11 Pile-sheet retaining wall
Retaining structure composed of members, e.g. anti-sliding pile and pile baffle.
2.1.12 Slope ratio method
Slope treatment method in which the overall stability of slope is maintained by adjusting and controlling the slope ratio and the stability of slope and slop surface is guaranteed by taking construction measures.
