Rapid Detection Method of Dr Value of Large Particle Size Filter Materials in Earth Rock-Filling Dam of NuoZhadu
On construction quality detection in high earth rock-filling dam, it is difficulty for testing the relative density Dr Value of large particle size filter materials. In this paper, we have effectively controlled the filling quality of filter material II in Nuozhadu core dam, and at the same time, explored and applied the rapid detection method of Dr Value of filter material II. Then studied the relationship between maximum, minimum dry density of the different grade material in the case of same compacted function and soil gradation parameters, and put forward a method of maximum and minimum dry density associated with particle composition, fitting relation curve between dry density and particle content less than 5mm(S5). By detecting the content of S5, it can be directly reached maximum and minimum dry density, and then calculate the Dr Value.
