Abstract
The invention discloses a detection and evaluation method for a high filling tamping foundation (shortened as DEHE Detection Evaluation Method). The detection procedures are as follows: firstly, the tamping construction of a first layer is made, then the soil layers of the tamping construction are approximately divided into a bottom layer, an intermediate layer and a surface layer to be detected, wherein, the detection of the bottom layer adopts a load test and a density test; the detection of the intermediate layer adopts a particle analysis test, a density test and a wave speed test; the detection of the surface layer adopts a load test, a density test, a wave speed test and a foundation resilience modulus test. The invention can greatly reduce the quantity of the detection, improve the detection efficiency, decrease the detection cost, and achieve the double effect.
Description
Technical field
The present invention relates to a kind of detection and evaluation method, particularly high embankment compacting foundation detects and evaluation method.
Background technology
China is the country in mountain area more than, along with expanding economy and national strategy to develop western regions are implemented, the air-transport industry development rapidly, the outlying mountain area of economizing such as Yunnan, Guizhou, Guangxi, Hunan, Hubei particularly, build, reorganization and expansion and the airport (particularly branch line airport) of planning be numerous.In above-mentioned area, the large-area height of ubiquity digs deep fill compacting foundation disposal field.
At present to the detection of high embankment compacting foundation treatment effect none method that packages still.Adopt in the routine, heavy dynamic penetration test detects, because of the boulder particle diameter is difficult to feeler inspection greatly; The land used pledge is visited and is detected, and can not satisfy the designer detects index to ground quantitative requirement; Adopt conventional density test to detect, the particle diameter D＜38mm that need banket, the indoor reality (standard or heavy type) of hitting is tested the maximum dry density value that can't record high fill foundation; Select for use load test to detect, big because of detecting the place, the detection test period is long, expense is high.Therefore, seek a kind of feasible technically, the duration is fast, quality good, the rational high embankment compacting foundation of cost detects and evaluation method, has become the urgent great technical task of being concerned about and being badly in need of solving of numerous owners.
Summary of the invention
The purpose of this invention is to provide a kind of high embankment compacting foundation detects and evaluation method, abbreviating DEHE as (detects and estimates Detection Evaluation, high embankment High Embankment) detects evaluation assessment, solve in the high embankment compacting foundation, the big heavy dynamic penetration of piece stone particle diameter detects and is difficult to feeler inspection, and the geology physical prospecting detects can not satisfy the designer detects the quantitative requirement of index to ground problem; And the Density Detection of solution high embankment compacting foundation routine, need satisfy the limitation of D＜38mm because of the particle diameter that bankets, the indoor reality (standard or heavy type) of hitting is tested the maximum dry density value problem that can't record high fill foundation, also will solve the conventional load test of high embankment compacting foundation and detect, the detection place is big, the detection problem that test period is long, expense is high.
The object of the present invention is achieved like this: a kind of high embankment compacting foundation detects and evaluation method, adopts different detection methods by different layerings in surveyed area, and concrete grammar is as follows:
Step 1, the strong rammer of first floor are finished;

Step 5, intermediate layer grain size analysis test detect;
Step 6, the test of intermediate layer wave velocity testing detect;
Step 7, surface layer density test detect;
Step 8, the test of surface layer wave velocity testing detect;
Step 9, the test of the surface layer ground modulus of resilience detect;
Step 10, surface layer load test detect;
Step 11, continuation placement in layers, dynamic consolidation construction repeat to detect step 2～step 10 after finishing.
Step 12, overall assessment.
Optimized technical scheme: in the above-mentioned steps 1, the dynamic consolidation construction layer thickness is generally 4m.
In the above-mentioned steps 2, underlayer thickness is 1.0m～1.5m, adopts douche to carry out density test and detects.
In the above-mentioned steps 4, intermediate layer thickness is 1.0m～1.5m, adopts douche to carry out density test and detects.
