Analyzing the characteristics of the contact line ′ s overlap in Ha-Da Railway briefly , the design problem of the contact line ′ s overlap on the electrified railway is proposed .

通过计算，求出整个锚段内接触线的延伸量、收缩量和直线拉出值，从而得出断线时接触线总预留长度。

And the extension amount , extraction amount and tangent line stagger of the contact wire in the whole tensioning section can be obtained by calculation , and then the total reservation length of contact wire before cutting can be obtained thereof .

当相对密度较高或锚碇段长度较长，于地锚达极限拉拔力时，其降伏范围也较大。

As relative density of soil or fixed length of an anchor increased , the yielding zone also expanded when the anchor was stressed to ultimate load .
