堆石混凝土长龄期力学性能试验研究

Experimental study on mechanical properties of long age RFC

基于实际工程的大坝堆石混凝土材料,采用切割大试件、超声回弹法、钻芯法等试验进行抗压强度、劈裂抗拉强度、弹性模量、声速值、回弹值等试验,从材料的力学性能、弹性模量、材料均匀密实性等方面进行研究,试验数据来源于经历14 a的长龄期堆石混凝土实际工程,研究结果可为堆石混凝土坝的应用推广提供借鉴作用。

Based on the dam RFC materials of practical engineering,this paper adopts cutting large specimens,ultrasonic rebound method,core drilling method and other tests to conduct compressive strength,splitting tensile strength,elastic modulus,sound velocity value,rebound value and other tests,and studies the mechanical properties,elastic modulus and uniform compactness of materials.The experimental data are from the 14-year old RFC project,and the research result can provide reference for the application and promotion of RFC DAMS.
