断面轮廓 meaning in English

profiled outline

Thin lines are used to draw the outlines of superposition cuts . when it overlaps the outlines of the view , the outlines must be drawn completely
其轮廓线用细实线绘制，当视图中的轮廓线与重合断面轮廓线重叠时，视图中的轮廓线仍然应连续画出不可间断。
This thesis pass through the laser delimitation instrument and the geological radar instrument means , to tunnel initial stages support and secondary structure . at past the research of tunnel lining thickness depend on opening dig figure , don " t consider the effect of tunnel lining inner figure . adopting the integrate method of the laser delimitation instrument and the geological radar could most exact reflect the change rule of tunnel lining thickness , but also could do lots unbroken examination , have very important for summing - up the rule of tunnel lining thickness change , and have very amplitude extend value
本文通过激光限界仪和地质雷达综合方法，对新建高速公路隧道初期支护和二次衬砌混凝土内轮廓和厚度进行了检测，对衬砌厚度的分布规律以往的研究中，多以开挖和衬砌的轮廓变化为依据，并未考虑衬砌内轮廓的影响，而采用激光断面轮廓限界仪和地质雷达综合方法能较为准确的反应衬砌厚度的变化规律，并且能够无破损的做大量的检测工作，为总结混凝土厚度的规律有很大作用，并有极大的推广价值。
