    本文通過激光限界儀和地質雷達綜合方法，對新建高速公路隧道初期支護和二次襯砌混凝土內輪廓和厚度進行了檢測，對襯砌厚度的分佈規律以往的研究中，多以開挖和襯砌的輪廓變化為依據，並未考慮襯砌內輪廓的影響，而採用激光斷面輪廓限界儀和地質雷達綜合方法能較為準確的反應襯砌厚度的變化規律，並且能夠無破損的做大量的檢測工作，為總結混凝土厚度的規律有很大作用，並有極大的推廣價值。
  6. It emphases the selection of secondary voltage of the step - down transformer, the control and protection of thyristor, the calculation of compensation capability and group capability, the technique of cross - zero switched on / off capacitors or reactor, the solution of avoiding possible resonance in switching on / off groups of capacitors or reactor and the measure of the best time to switch ( including the design of the computer survey and control system, instrument deliver system, delay operate and protect system ). although thyristor as a no - contact switch can avoid almost the problem of contact switch with contact, it can not solve the over - voltage, over - current and transient process itself as switching on / off capacitors or reactor. so we must develop a set of thyristor - switched control and protect system with great reliability so that it can realize of cross - zero switching on / off capacitors or reactor at any time
