Description
Technical field
The present invention relates to engineering geological investigation technical field, and specifically surrounding rock category becomes more meticulous in a kind of hydraulic power project
Sorting technique.
Background technology
At present, in hydraulic power project, the Engineering Geology Classification of country rock is largely used《Middle-size and small-size hydraulic power project
Geological mapping specification》(DL/T5410-2009) with《Hydraulic power project geological mapping specification》Required in (GB 50287-2016)
Water power rocvk classification HC methods.HC methods are using rock strength, rock mass completeness and structure surface state as Fundamentals, with underground water
And the occurrence of primary structure face is modifying factor, using the cumulative score of Fundamentals and modifying factor as Basic Criteria, strong with country rock
Spend stress ratio and carry out surrounding rock category division to limit criterion.Find during live country rock scoring, different Geological Engineerings
Scoring of the teacher to identical country rock section is there are significant difference, or even surrounding rock category occurs and judge different situation, to live ground
Smooth carry out of matter work exerts a certain influence.
To find out its cause, in the five big scoring factors of water power rocvk classification HC law regulations, rock strength, rock mass completeness and
The score value of three factors of groundwater state is provided by section, and interval is larger, as shown in table 1~3.
1 rock strength of table scores
2 rock mass completeness of table scores
3 groundwater state of table scores
Maximum interval reaches 10 points in above table, in practical operation, because of the master between geomatics engineer individual
It is inevitable to see difference, so as to cause scoring of the different geomatics engineers to identical country rock section there are significant difference, or even goes out
Surrounding rock category is showed and has judged different situation, exerted a certain influence to smooth carry out of field geology work.
Due to diversity of values mainly due to the scoring interval of the partial evaluation factor it is big caused by, so to reduce not
With the diversity of values of geomatics engineer, most directly effective method is to reduce the scoring interval of foregoing three scorings factor.
The content of the invention
The present invention provides engineering of surrounding rock geology in a kind of hydraulic power project and becomes more meticulous sorting technique, solves existing water power and encloses
The scoring interval of the rock classification HC method partial evaluation factors is big, and diversity of values is obvious accordingly for different geomatics engineers, influences to enclose
The problem of rock kind judging.
The technical solution adopted by the present invention to solve the technical problems is：Engineering of surrounding rock geology is fine in hydraulic power project
Change sorting technique, including rock strength refinement scoring, rock mass completeness refinement scoring and groundwater state refinement scoring.Its
In, rock strength refinement scoring is carried out by table 4, and rock mass completeness refinement scoring is carried out by table 5, groundwater state refinement scoring
Carried out by table 6.
4 rock strength of table refines grade form
5 rock mass completeness of table refines grade form
6 groundwater state of table refines grade form
The beneficial effects of the invention are as follows：Engineering of surrounding rock geology becomes more meticulous sorting technique in hydraulic power project, is based on《It is medium and small
Type hydraulic power project geological mapping specification》, commented with reference to the achievement that the actual geological conditions in scene and field investigation method obtain
Valency, is dissolved into country rock refinement by geologic feature in area and field investigation method (hammering method, excavate shaping and residual porosity etc.) and scores
In, the standards of grading for being adapted to engineering practice are formulated, the accuracy of correlation engineering surrounding rock category division can be effectively improved, are reduced
The influence of human factor, makes the division of Wall Rock of Tunnel more tally with the actual situation, and on the premise of engineering construction safety is ensured, makes work
The construction of the diversion tunnel of journey project critical circuits has obtained effective control in terms of investing with progress, and strong operability, has
Higher practical value and larger economic benefit.
Embodiment
Engineering of surrounding rock geology becomes more meticulous sorting technique in hydraulic power project, including rock strength refinement scoring, rock mass are complete
Whole degree refinement scoring and groundwater state refinement scoring.
In scoring rock strength refinement, based on formation lithology in Project Areas, with reference to live hammering method, cavern excavation
The features such as the water sensitivity that shaping situation, residual porosity and rock mass are shown are evaluated, and evaluation meets specification, strong operability, such as
Shown in table 4.
Rock mass completeness refinement grade form considered structural plane in rock mass structure, rock mass development group number and its with
The angle of hole axis, the development condition of weak intercalated layer, the cavern excavation shaping rock mass completeness such as situation and residual porosity influence because
Element, as shown in table 5.
Groundwater state refinement scoring is influenced by field working conditions condition, and the pressure head of underground water is sometimes difficult to measure,
Groundwater activities state in tunnel can judge according to water yield.Groundwater state refinement scoring combines《Classification of Engineering Rocks
Standard》(GB/T50218-2014), groundwater activities state is divided into 7 kinds, the interval corresponding to various states is reduced to
No more than 2 points, point poor smaller, it is easier to accurate marking evaluation, as shown in table 6.
In order to examine above-mentioned table 4~6 to refine the effect of grade form, spy arranges field geology personnel after learning to table 4~6
Scored the country rock of different lithology, different rock mass structures and different groundwater state hole sections in certain power station, such as the institute of table 7
Show.According to statistical result, different geological personnels are substantially reduced for the diversity of values of same section of country rock, essentially eliminate country rock class
Different situations is not divided.
Table 7 becomes more meticulous the personal scoring statistical form of division methods
