摘 要

[摘要]中國目前與地鐵運(yùn)行引起的建筑物室內(nèi)環(huán)境振動(dòng)相關(guān)的規(guī)范和標(biāo)準(zhǔn)約有十余種,國外也有多種針對人體全身振動(dòng)的相關(guān)規(guī)范。各規(guī)范和標(biāo)準(zhǔn)針對城市軌道交通引起的環(huán)境振動(dòng)提出了嚴(yán)格和詳細(xì)的要求,包括環(huán)境振動(dòng)的測量方法、評價(jià)量的計(jì)算方法和適用條件及城市各類區(qū)域的振級評價(jià)量限值。但各規(guī)范和標(biāo)準(zhǔn)在上述各方面存在差異,給工程應(yīng)用帶來一定程度的混亂。首先梳理了不同規(guī)范和標(biāo)準(zhǔn)中測量方法、評價(jià)量和限值的異同,再通過MATLAB程序試算道路交通及城市軌道交通引起的建筑物內(nèi)樓板中央的垂向振動(dòng)加速度時(shí)程,比較不同規(guī)范和標(biāo)準(zhǔn)對環(huán)境振動(dòng)要求的嚴(yán)格程度和適用范圍,最后提出一些針對現(xiàn)有規(guī)范和標(biāo)準(zhǔn)的改進(jìn)建議。

Comparative research on urban rail transit-induced building vibrations related specifications

Abstract:There are a dozen of specifications and standards related to the subway-induced environmental vibration currently in China. And there are also several specifications about human body vibration issued by other countries or international organizations. All those specifications and standards regulate strict and detailed requirements to the urban rail transit-induced environmental vibrations, including measurement method of vibrations, the calculation methods of vibration assessment value and applicable conditions, and vibration assessment value limit of various type of urban area. But the differences in the above aspects between these specifications and standards bring a certain degree of chaos in the enginering practice. Firstly the similarities and differences about measurement method, evaluation and allowable limits of these specifications and standards were summarized. Then, the MATLAB program was used to calculate the vertical vibration acceleration time history at the center of the indoor slab induced by road traffic and urban rail transit respectively to compare the degree of rigor and the scope of application among these specifications and standards. At last, some recommendations for the improvement of existing specifications and standards were suggested.

Keywords:subway;  indoor environmental vibration; specification; standard; vibration level
