An in-situ experiment on the RCC with thick placement lift for the construction of Madushan Hydropower Station on Red River in Yannan Province is made, and moreover, the compared tests on the different lifts of the thich placement are also carried out for the actual condition of the construction of Madushan Hydropower Station on the basis of the experiment ever made in the construction of the RCC with thick placement lift for Huanghuazhai Hydropewer Station. During the construction and experiment, SD451 vibratory roller with vertical vibration mechanism provided by Sakai Heavy Industries, Ltd in Japan, the nuclear moisture density gauges developed by Soil and Rock Engineering Co. Ltd. , in Japan, i. e. , the nuclear density gauge developed by CPN in USA are adopted. In the experiment, the compared tests on the properties of the measuring instruments for the testing of the RCC with thick placement lifts are emphatically conducted for the remedy of the defects from the measuring instruments for the relevant tests during the construction of Huanghuazhai Hydropawer Station, so as to select the simple and convenient measuring instruments with higher performance-price ratio for the construction of the project concerned.
