Description
Technical Field
The invention relates to the technical field of vibration reduction and isolation on a propagation path, in particular to an inverted trapezoidal pile vibration isolation barrier and a construction method thereof. The vibration isolator is suitable for passive vibration isolation of environmental vibration caused by traffic, construction and the like.
Background
In recent years, with the rapid development of industrial modernization, the problem of environmental pollution is prominent, wherein environmental vibration has attracted people's attention and is internationally listed as one of seven public hazards, mainly caused by traffic vibration of roads, railways and the like, vibration of large-scale mechanical equipment, dynamic compaction construction and the like. The study shows that the far field surface wave energy ratio is large, and fig. 10 is an energy distribution graph along the normalized depth at a typical far field under a certain unit load, wherein LRIs the Reuli wavelength and z is the depth from the earth surface; it can be seen that 0.5L from the ground surfaceRAnd 1.0LRThe energy content of the water reaches 50.9 percent and 67.1 percent respectively. It can be seen that ground vibration is dominated by surface waves.
In order to reduce the influence of environmental vibration, the propagation path of vibration wave can be cut off, and a vibration isolation barrier is arranged on the propagation path between a vibration source and a vibration receiver; the barrier has the advantage of not influencing the use of the vibration source and the vibration receiving body, and is particularly suitable for some established projects. The vibration isolation barrier generally comprises a continuous barrier and a discontinuous barrier, and a vibration damping area is formed behind the barrier by utilizing the phenomena of reflection, refraction, interference and the like of vibration waves, so that the aim of vibration damping is fulfilled. The continuous barrier has a function of reflecting and absorbing the vibration wave in the full section, and thus generally has a better vibration isolation effect than the discontinuous barrier.
The continuous barrier may be divided into empty and filled trenches. The empty trench has the best vibration isolation effect because the empty trench completely cuts off the propagation path of the vibration wave; however, in practical engineering, the practical application is limited due to the stability problem of the trench wall, particularly for high water level areas, underground water permeates into the trench, and the vibration isolation effect of the empty trench is reduced due to the fact that water is used as a propagation medium to propagate compression waves. The filling trench is widely adopted because the filling trench is not limited by the trench depth, the vibration isolation efficiency is not only related to the trench depth and the trench width, but also related to the impedance ratio between the filling material and the soil body, the larger the impedance ratio is, the better the vibration isolation effect of the filling trench is, and the filling trench can be divided into a soft filling trench (such as a rubber and polyethylene foam filling trench) and a hard filling trench (such as a concrete filling trench) according to the relationship between the impedance ratio and 1; however, the filling trench is usually designed to have a rectangular cross section, and has the disadvantages of large engineering quantity, high material consumption and the like in actual construction.
