摘要:
针对道路混凝土中钢筋网对振动能量的阻隔,通过采集、比较振动加速度和测定分层密度等方法,研究振动能量在混凝土中(钢筋网上、下)的传播情况.研究表明:经过单层钢筋网的阻隔,振动能量水平方向上约衰减12％,竖直方向上约衰减19％；钢筋网的存在对其上混凝土的振动密实无显著影响,对其下混凝土有较大影响；振动频率和振动延续时间是影响振动能量衰减系数的关键因素,适当的增大振动频率、延长振动延续时间可以有效的减小能量衰减.
Abstract:
By collecting coMParing vibration acceleration and determining density stratification,the propaga-tion of energy in the concrete was studied to to reflect vibration barrier of road concrete from steel mesh. Theresults indicate that: vibration energy attenuation in horizontal direction is about 12%,meanwhile in verticaldirection is about 19% through single steel mesh;Steel mesh has no significant effect on concrete above steelmesh,but has great significant effeet on concrete blow steel mesh;Vibration frequency and time greatly affectcoefficient of vibration energy attenuation,and appropriately increasing frequency or time can effectively re-duce the energy attenuation.
