Construction method of novel vibration isolation barrier based on non-uniform layer and wave resistance plate
The invention discloses a construction method of a novel vibration isolation barrier based on a non-uniform layer and a wave resistance plate. The method comprises the following steps that S1, the non-uniform layer and the wave resistance plate are embedded between a structure to be protected and a vibration source caused by various environmental vibrations to form the vibration isolation barrier;and S2, each layer of material in the non-uniform layer and the wave resistance plate is selected according to the ratio of the wave impedance of a barrier material to the wave impedance of foundation soil, and the larger the wave impedance difference between the wave resistance plate and a foundation soil medium is, the more ideal the vibration isolation effect is; and S21, the first layer is areinforced concrete plate with the relative foundation soil wave impedance ratio at 103 level, and the second layer is a foam plastic plate with the relative foundation soil wave impedance ratio at 10-3 level. According to the method, the transmission and reflection coefficients of elastic waves at the foundation soil medium and different wave resistance plate interfaces can be optimally designedand adjusted according to the parameters of the foundation soil medium in regions, so that the wave resistance plate design has operability and controllability.
本发明公开了一种新型的基于非均匀层和波阻板隔振屏障的构建方法，包括如下步骤：S1在拟保护的结构物和各种环境振动引起的振源之间埋置非均匀层和波阻板形成隔振屏障；S2根据屏障材料的波阻抗与地基土波阻抗的比值选择非均匀层和波阻板中的每层材料，波阻板和地基土介质的波阻抗差异越大，则隔振效果越理想；S21选择第一层为相对地基土波阻抗比在103级别的钢筋混凝土板，第二层为相对地基土波阻抗比在10‑3级别的泡沫塑料板。本发明可以根据所在区域地基土介质的参数，优化设计调节弹性波在地基土介质和不同波阻板界面处透反射系数的大小，使波阻板设计更具有操作性和可控性。
