第四节运输工程构筑物一、一般规定4.1 本节规定适用于地震烈度为7度、8度及9度地区内的Ⅰ～Ⅳ级铁路,Ⅰ～Ⅳ、Ⅲп及Ⅳп级公路,地下铁道,城市高速公路及干线街道的设计.注:1.用于运输工程的生产厂房、辅助用房、仓库及穴它建筑物,应按本规范第2节及第3节的有关规定来设计.2.在设计V级铁路及工业企业铁路线上的构筑物时,其地震荷载可根据设计批准部门同意的意见来计算.4.2 本节规定了计算地震烈度为7度、8度及9度的运输工程构筑物设计的特殊要求.运输工程构筑物的计算地震烈度,按本节第4.3条的规定进行确定.
Section 4 Transport Engineering Structures I. General Provisions 4.1 The provisions of this Section apply to Grade I-IV railways in areas with seismic intensity of 7 degrees, 8 degrees and 9 degrees, I-IV, III-P and IV-P class highways, underground railways, and urban high-speed Design of highways and trunk streets. Note: 1. Production plants, auxiliary houses, warehouses and other structures used for transport engineering should be designed in accordance with the relevant provisions of Sections 2 and 3 of this Code. 2. When designing a V-railway and industrial enterprise on a railway line, the seismic load can be calculated based on the opinion agreed by the design approval department. 4.2 This section specifies the design of transportation engineering structures for calculating seismic intensity of 7 degrees, 8 degrees and 9 degrees. Special requirements. Calculated seismic intensity of transport engineering structures is determined according to the provisions of Article 4.3 of this section.
