Construction method for open trench vibration isolation barrier
The invention is applicable to the technical field of building construction, and provides a construction method for an open trench vibration isolation barrier. The construction method comprises the following steps that the construction position of the open trench vibration isolation barrier is determined according to the position relation between a seismic source and a to-be-vibration-isolated building; the wavelength LR of a rayleigh wave is determined according to a medium parameter of a site soil body where the construction position is located; a plurality of spaced open trenches are excavated in the construction position according to the wavelength LR of the rayleigh wave; and the depth of the open trenches is 0.5 LR - 0.7 LR, and the distance between the centers of the bottom surfacesof every two adjacent open trenches is 0.9 LR - 1.1 LR. According to the construction method for the opening trench isolation barrier, the plurality of spaced open trenches are arranged, the spacingbetween the open trenches is further defined, and the coupling effect between the plurality of open trenches is reserved to the greatest extent, so that the depth of the open trenches is only requiredto be the wavelength of half the rayleigh wave while the vibration isolation effect is achieved, the requirement for the depth of the open trenches is greatly reduced, the project construction cost is greatly reduced, and the stability of the open trenches is improved.
本发明适用于建筑施工技术领域，提供了一种空沟隔振屏障的施工方法，所述方法包括：根据震源以及待隔振建筑物的位置关系确定空沟隔振屏障的施工位置；根据施工位置所处的场地土体的介质参数确定瑞利波的波长L；根据瑞利波的波长L在施工位置挖掘出多个间隔的空沟；所述空沟的深度为0.5L~0.7L，且相邻的两个空沟底面中心之间的距离为0.9L~1.1L。本发明实施例提供的空沟隔振屏障的施工方法，通过设置多个间隔的空沟，并进一步限定了空沟之间的间隔，最大限度保留了多个空沟之间的耦合作用，使得在实现隔振效果时对沟深的要求仅仅为半个瑞利波波长，大大降低了对空沟深度的要求，大大降低了工程的造价，提高了空沟的稳定性。
