前言伟大领袖毛主席教导我们:“打破洋框框,走自己工业发展道路。”“独立自主、自力更生”。本算例系按照叁桥综002道碴桥面钢筋混凝土梁耳墙式桥台的设计原则编写的。该图采用了我院与兄弟单位共同工作所取得的一些初步科研成果,吸取了以往施工,营运及设计方面的经验,打破了部份脱离实际的现行桥规框框。但是有的计算公式及办法虽在文化大革命中对它提出了批评的意见,但到目前尚未有新的、经过实践考验的公式及办法来代替它,例如土压力公式等等。因此,在本算例中部份仍沿用以往常用的计算办法进行设计。由于我们对打破桥规方面的工作做得很少,很不够,吸收群众的意见不够广泛,提出的改进意见不完全恰当,有的也可能是错误的,希望同志们提出宝贵意见,共同研究使之逐步提高,渐趋完善。
Foreword Chairman Mao, the great leader, teaches us: “Breaking the framework of the world and taking the path of industrial development.” “Independent and self-reliant.” This example is based on the design principles of Sanqiao Comprehensive 002 Ballastless Deck Reinforced Concrete Beam wall abutment design. This figure uses some preliminary research achievements made by our institute in working with fraternal units and draws on the past experience in construction, operation and design, breaking some of the existing bridge rules. However, some formulas and methods of calculation have criticized it in the Cultural Revolution, but so far no new and tried-out formulas and measures have been put in place to replace it. For example, earth pressure formula and so on. Therefore, some of the calculations in this study are still used in the design. Since we have done very little, not enough to break the bridge regulations, not enough people to absorb the opinions of the masses, the proposed improvements are not entirely appropriate and some may be wrong. We hope that comrades will come forward with valuable suggestions and joint research Gradually improve, gradually improving.
