摘　　要：新建黄大线岭庄线路所的信号设计方案证明通过灵活利用既有区间的轨道电路分割点,可以有效减少插入分歧道岔对该区间信号布点的广泛影响,避免轨旁信号设备的大范围迁改,进而显著节省投资成本。依托该行车和线路模式,从技术难点、人员配置和工程投资等方面分析独立联锁控制、纳入邻站直接控制、区域联锁控制这3种线路所联锁控制方式的优缺点。The signaling system design scheme of Lingzhuang block post at the newly built Huang-Da railway proves that by fl exibly using the existing cut points of sectional track circuit,the infl uence of inserting branching turnout on the sectional signal distribution point can be eff ectively reduced,the wide range of relocation of trackside signal equipment can be avoided,thus the investment costs can be signifi cantly saved.Based on the train operation and railway line mode,the advantages and disadvantages of the three interlocking control modes for block post,which are independent interlocking control,directly controlled by adjacent station and regional interlocking control,are analyzed from the aspects of technical diffi culties,personnel allocation and engineering investment.
