Multi-row vibration isolation trench barrier structure and vibration isolation effect evaluation method
According to the multi-row vibration isolation trench barrier structure and an isolation effect evaluation method. A main body structure of the multi-row vibration isolation trench barrier structure is empty trenches or filling trenches, the cross sections of vibration isolation trenches are non-rectangular, and the row number is larger than 1; as for the filling trenches filled with wave isolation materials, the number of rows is two or three; and the cross sections of the vibration isolation trenches comprise an isosceles triangle, a right triangle, an isosceles trapezoid and a right trapezoid. By means of the multi-row vibration isolation trench barrier structure, the vibration isolation effect of the vibration isolation trenches can be improved, the problems that a traditional rectangular hollow trench needs too large depth and is high in construction difficulty are further solved, the vibration isolation effect the same as or better than that of the traditional vibration isolationtrench can be achieved by using multiple rows of novel vibration isolation trenches with small depth, and therefore the practicability of a trench barrier in actual vibration isolation engineering isimproved.
一种多排隔振沟屏障结构及隔振效果的评价方法，其主体结构为空沟或填充沟，所述隔振沟的横截面为非矩形、排数大于1、填满隔波材料的填充沟；所述排数包括双排或三排；所述隔振沟横截面型式包括等腰三角形、直角三角形、等腰梯形和直角梯形。本发明能提高隔振沟的隔振效果，进一步改善传统矩形空沟需要深度过大、施工难度大等问题，可以通过使用多排较小深度的新型隔振沟达到与传统隔振沟相同或更好的隔振效果，以此增加了沟屏障在实际隔振工程中的实用性。
