中心城区电力电缆隧道线路设计初探

Discussion on Design of Electric Power Cable Tunnel Line of Central City Area

随着城市建设的不断发展、城市化程度不断提高,导致用电负荷快速增长,大截面电缆输电方式逐渐得到广泛应用;同时,随着人们对环境、景观的高标准要求,在中心城区架空敷设电缆已无可能,采用电力电缆隧道敷设大截面电缆得到推广。针对中心城区地下构筑物众多、地下空间紧张的复杂地下环境,初步讨论如何合理的选择电力电缆隧道的走向及线路,切实可行实施大截面电力隧道,确保满足中心城区用电负荷的快速增长的同时,最大限度降低电力电缆隧道施工、运营期间对城市环境、景观等方面的影响。

With the continuous development of city construction and the continuous improvement of urbanization level to result in the rapid increment of electricity load,the large section of cable electric power transmission mode is gradually widely used.At the same time with the high standard requirement of environment and landscape by the people,it has been impossible to elevate the cable in the central city area,but the electric cable tunnel used to lay the cable is popularized.Aiming at the complex underground environment of more underground buildings and limited underground space in the central city area,the article preliminarily discusses how to reasonably select the alignment and line of electric cable tunnel,feasibly implement the large section of electric tunnel,ensure the rapid increment of electricity load in the central city area,and minimum the influence of electric cable tunnel construction and operation periods on the city environment and landscape.
