'3.1 USES OF FLOATING SLAB TRACK IN VIBRATION CONTROL,3.2. Floating slab tract,3.3.1 Introduction,The development of the Floating slab track (FST) systems has started long years ago. It has been put in use over forty years on rail transit systems around the world. Their implementation is to control ground-borne noise and vibration that would otherwise cause negative environmental impacts. Some authors also refer to the FST as a Mass Spring System (MSS). It’s basically consisting of concrete slabs supported on resilient elements such as rubber bearings, glass fiber or steel- springs. This have been used to control vibration from underground trains for years. The design is aimed to reduce vibrations transmitted to the supporting foundations via the resilient elements. The slabs can be cast in situ, leading to a continuous length of concrete slab, or can be constructed in discrete precast sections connected by construction joints Floating slab track system is a special type of track structure that is beyond the normal designs. The floating slab is an additional concept and requirement to normal track structure. The structure design must allow for floating slabs where they are needed, as the floating usually requires additional invert depth.,3.3.2 Types of floating slab system,The floating slab system is consisting of two basic types;,1) Cast-in-situ floating slabs, which is constructed by placing a permanent sheet metal from on elastomer isolators and filling the form with concrete. The floating slabs measure approximately 6m or more along the track and 3m transverse to the track. The depth of the slab generally ranges from 300 to 450 mm. some construction techniques involve using the tunnel invert as a form for the slab, then jacking the slab to design elevation.,2) Discontinuous “double tie” precast floating slabs, which is measured about 1.2 to 1.5 m along the track and 3m transverse to the track. The depth, and thus the mass, of the slab may vary from about 200 to 600 mm. the weight of the slab may range from 2 to 7 tons. The most common configuration is with 1.8 tons slab that is 200mm thick. The slabs are referred to as double ties because they support each rail with two direct fixation fasteners, giving a total of four direct fixation fasteners per slab.'

3.1浮板轨道在振动控制中的应用,3.2。浮板梁,3.3.1简介,浮板轨道（FST）系统的开发早在多年前就开始了。它已经在世界各地的轨道交通系统上使用了40多年。它们的实施是为了控制地面噪声和振动，否则会对环境造成负面影响。一些作者还将FST称为质量弹簧系统（MSS）。它基本上由混凝土板组成，由弹性元件支撑，如橡胶支座、玻璃纤维或钢弹簧。多年来，它一直被用来控制地下列车的振动。该设计旨在减少通过弹性元件传递到支撑基础的振动。板可现浇，形成连续的混凝土板长度，也可在施工缝连接的离散预制段内施工，浮板轨道系统是一种特殊类型的轨道结构，超出了正常设计范围。浮板是普通轨道结构的一个附加概念和要求。结构设计必须考虑到需要浮板的地方，因为浮板通常需要额外的仰拱深度。,3.3.2浮板系统类型,浮板系统由两种基本类型组成；,1）现浇浮动板，通过在弹性体隔振器上放置永久性金属板并用混凝土填充模板来建造。浮板沿轨道约6米或更长，与轨道横向3米。板的深度一般为300至450 mm。一些施工技术包括使用隧道仰拱作为板的模板，然后将板顶升到设计标高。,2）不连续的“双系杆”预制浮板，沿轨道测量约1.2至1.5 m，与轨道横向测量约3 m。板的深度和质量可能从大约200到600 mm不等。板的重量可能在2到7吨之间。最常见的配置是1.8吨厚200毫米的平板。板被称为双扎带，因为它们用两个直接固定紧固件支撑每根轨道，每个板总共有四个直接固定紧固件。。
