Issued by the National Energy Administration
Foreword
According to the "Notice of the National Energy Administration on Issuing the.2015 Energy Sector Industry Standard System (Revision) Plan" (National Energy Administration)
Neng Technology [2015] No. 283) requirements, the procedure preparation team has conducted extensive investigations and studies, carefully summed up practical experience, and
Based on extensive solicitation of opinions, this regulation was revised.
The main technical content of this regulation is. dam site engineering geological survey content, dam site engineering geological survey method, dam foundation
Engineering geological characteristics research, dam site engineering geological evaluation, dam site construction geology.
The main technical content of the revision of this regulation is.
--Added relevant regulations on engineering geological survey of dangerous rock masses on natural slopes surrounding buildings at the dam site.
--Added relevant regulations on dam foundation excavation slack monitoring.
--Added relevant regulations for special engineering geological research on rock foundations such as altered rock and deep unloading rock mass.
- Added relevant regulations on the classification of debris flows according to the landform characteristics of the catchment area.
--Relevant regulations on dam site construction geology have been revised, and the original regulations "geological work of dam foundation treatment" and "geological monitoring
Work" is merged into "construction geological work".
--Relevant regulations on the classification of rock mass compactness have been revised.
- Relevant regulations on the identification of collapsibility of loess have been revised.
- Relevant regulations on the discrimination of soil seismic liquefaction have been revised.
-Deleted the original regulations "landform type division", "layered rock layer thickness division" and "rock mass structure surface gauge"
Model classification" "Rock mass weathering zone division" "Rock mass unloading zone division" "Debris flow is classified according to fluid properties and the relationship between debris flow
Engineering classification" "Rock and soil permeability classification", "Rock mass in-situ stress classification", "Rock quality classification", "Rock mass structure type"
Divide the appendix content of "Rock structural surface property classification and shear (fracture) strength value" and "Soil classification standard".
