摘要

利用地震加速度计测量了沙波大坝建设工程中的峰值粒子速度(PPV) mm / sec。本研究是确定施工设备产生的PPV值,然后与BS 6472-2: 2008标准进行比较。测量方法是根据适用的规则进行的。每台机器产生的PPV测量结果是不同的。在重型设备自卸卡车、挖掘机和前端装载机PPV显示值在50米的距离,100米,150米和200米在安全条件下指的是标准仍在时间间隔为0.2 - 0.4毫米/秒的范围虽然打桩设备,拆除,振动打桩机在50米的距离是在不安全的条件下,因为超过0.2 - 0.4毫米/秒的范围,但是在100,150,和200 PPV值安全conditionKey的话:PPV,地面振动,大坝振动

ANALISIS GROUND VIBRATION DENGAN METODE PEAK PARTICLE VELOCITY (PPV)

Measurement of Peak Particle Velocity (PPV) mm / sec in the Sabo dam construction project was carried out using seismic accelerometers. This study is to determine the value of PPV produced by construction equipment and then compared with the BS 6472-2: 2008 standard. The measurement method is carried out based on the applicable rules. PPV measurement results produced by each machine are different. In heavy equipment dump trucks, excavators, and front end loaders show PPV values at distances of 50 m, 100 m, 150 m and 200 m under safe conditions referring to the standard which is still in the range of 0.2 - 0.4 mm / sec. while for the pile driving device, demolition, vibrator pile driver at a distance of 50 meters are in unsafe conditions, because more than the range of 0.2 - 0.4 mm / sec, but at a distance of 100, 150, and 200 m PPV values are at safe condition


Key words: PPV, Ground Vibration, Dam sabo
