（2）坚持技术先进性、科学合理性、经济适用性、安全可靠性与工程施工环境相结合的原则。

（3）对施工现场坚持全员、全方位、全过程严密监控，动态控制，科学管理相结合的原则。

3、编制范围

适用于DK169+700-DK185+000段范围内路基贯通地线、电缆槽及护肩工程施工。

4、工程概况

中铁二十局深茂铁路JMZQ-4标一分部起讫里程DK169+700-DK185+000，管段全长公里，其中路基长度为公里。全线贯通地线、电缆槽及护肩各总长约18km。

综合接地系统是将沿着铁路线路两侧不同用途和不同电压的电气化、电力、通信、信号设备及其他金属构筑物的地线有机、合理的结合起来进入贯通地线，以保证铁路各系统、各设备之间实现等电位连接，减少不同设备、不同系统之间存在的电位差及可能造成的人身和设备的安全隐患（尤
