Research On The Apply Of Rock-filled Embankment Technology To Highway In Mountainous Area

With the rapid development of the road constructions in western China. The rock-filled embankment took one kind of ideal embankment form to obtain the widespread application. However existing compactness examination technology oneself cannot adapt the highway fast development request. Moreover, the body this modeling parameter which obtains by the experiment also often cannot be satisfying. Therefore studies one kind fast, lossless, the accurate embankment compactness examination technology and the development embankment slope protection new structural style research has the important theory and the project use value.This article will carry on the reorganization analysis by each kind of obtainable material to our country in recent years, and based on this conducts the systematic thorough research to the padding project nature and the new slope protection on the configuration type. This article laboratory test anticipates the hillside earth stone take the Lianhua to Tongan highway rock-filled to mix the padding as a material, studies the more reasonable indoor compaction method, the water content to the compacted density influence, the padding the thick smalls proportion to the compacted density influence and so on, and contrasts the rejection gradation law, the similar gradation law and the structure analytic method determined that the most going all out density the difference, then the determination padding most goes all out the density. The analysis rock-filled embankment reasonable compaction standard, the theory proves and determined that key subside the quantity, the rate of setting to control the compact effort and compactness method. Also has is the side slope code builds, in the former code builds is only considered that the code builds may reduce the side slope in the external environment corrosion, builds in here from mechanics angle the side slope code level achievement the structure regarding of rock-filled embankment. For further promotes the application to the new slope protection structure, this article specially has carried on the discussion to the gabion slope protection's characteristic and the craft as well as the examination. Finally, unifies the Guangxi Lianhua to Tongan highway's actual subsidence and the earth pressure data, has conducted the research to embankment's stability, finally indicated that this article proposed the rock-filled embankment is stable, and can satisfy the project actual request, has the certain project use value.Present paper's research results have provided the basis to the construction of rock-filled embankment and the stability analyses, has laid the foundation for the next rock-filled embankment construction and the development.
