厦漳跨海大桥南汊引桥施工期爆破震动监控与分析

Monitoring and Analysis of Blast Vibration for Nancha Approach Bridge of Xiazhang Sea-Crossing Bridge Under Construction

爆破震动对在建重大构筑物的影响不容忽视,以厦漳跨海大桥南汊引桥施工期爆破监测项目为依托,使用TC—4850爆破测振仪采集南汊引桥各构件在爆破地震荷载作用下的振动速度、振动频率等控制参数,分析爆破地震荷载对引桥施工过程中的作用和影响,评价引桥在爆破地震荷载作用后的健康状况并对后续的爆破监控提供依据。

The influence of blast vibration on major construction-in-process cannot be ignored. Based on blast monitoring project of Nancha Approach Bridge of Xiazhang Sea-Crossing Bridge, TC--4850, a measurement instrument for blasting vibration is used to collect vibration speed, vibration frequency and other control parameters of various components of Nancha Approach Bridge under the blasting seismic load which is used to analyze the effect and impact on the construction process of approach bridge, then evaluate the health condition of approach bridge after the blasting seismic load taken effect and provide the basis for the subsequent blasting monitoring process.
