摘要
选取在建的太原轨道交通2号线中"双塔西街—大南门"路段,采用国家现行标准进行运营期环境振动预测分析与评价。针对区间内环境振动敏感目标分别进行Z振级预测、室内二次结构噪声预测、文物振动速度预测,预测模型根据车辆、轨道及地质条件选择参数并确定。预测结果表明:9处敏感目标振级预测中,近轨LV,z10或LV,zmax预测值均存在超标;4处敏感目标室内二次结构噪声预测中,1处昼间超标,3处夜间超标;3处文物振动速度预测中,2处存在超标。
The vibration prediction and evaluation of operating period are carried out between Shuangtaxijie to Dananmen in line 2 of Taiyuan metro under construction by current relevant national standard.Z-weighted vibration level,indoor secondary air-brone noise,and vibration velocity of the cultural relics are predicted in the vibration-sensitive objectives in the interval between Shuangtaxijie to Dananmen,and prediction models and parameters are determined on vehicle,track and geological conditions.The prediction results show that the predicted near-orbit L V,z10 or L V,z max is more than the standard value in 9 vibration-sensitive objectives,the predicted values for 1 objective in daytime and 3 objectives at night exceed the standard value for indoor secondary structure noise of 4 sensitive objectives,and the predicted values for 2 objectives exceed the standard value for the vibration velocity of 3 cultural relics.The corresponding measures are proposed to reduce vibration on the basis of the evaluation results.
