施工准备工作必须在工程施工之前全部完成。（）

Students learn their lessons in class. In class teachers teach them. Students sit in the classroom listening to the teacher. This is a way of learning. Is this the only way for students to learn something? Of course not. There is another way to learn: students can teach themselves. For example, if you can’t remember something when you are doing your homework, you can look at your book to find the answer. This is a way to teach yourself. And it is not a difficult thing. We can do this at any place and at any time.

How do you teach yourself? The first thing you must do is reading. Read something you are interested in. or you have to read. The second is that you must ask yourself questions. The question is something you don’t understand, or you want to know more about. You can write down these questions. A clever student is usually good at asking questions. The third is to answer the question yourself by thinking hard, by reading the passage or other books, and sometimes by asking other people. This is the way of teaching yourself. And you must do this all by yourself. If you keep doing like for a long time, you are sure to succeed in your study.

某施工企业承建一双线铁路工程，该段全长70公里，合同工期30个月。其主要工程有：桥梁22座，均为明挖基础，上部结构有一座桥主跨为2×96米栓焊桁梁，其余均为32米双线单箱梁，共680孔，现场设两个预制梁场；双线隧道5座，围岩均为Ⅲ、Ⅳ级石灰岩，其中最长隧道为4．8公里；车站一座，站场土石方100万立方米，区间土石方1200万立方米，涵洞l60座。车站位于标段中部，东段分别有箱梁400孔，栓焊桁梁2孔，栓焊桁梁桥（可过箱梁）距车站3公里；仅车站附近具备建梁场条件；西段有箱梁280孔，其中在长隧道西端有l20孔，仅在长隧道东端有建梁场条件。隧道的平均月进度为100米，架梁进度为每天-孔。施工队伍进场后，由于征地拆迁工作的影响，所有工程开工时间比原计划滞后三个月。

由于箱梁宽度比隧道断面宽，箱梁架设要通过隧道，应采取什么措施？
