在井底车场设计中，受众多因素的影响，经常遇到将交岔点转角布置得较小（小于４０°左右）的情况。由于交岔点转角小，在作交岔点施工图时，有两个技术参数（图１中Ｌｘ，δ）的计算公式在《采矿设计手册》中并未给出，而这两个技术参数在井底车场闭合验算及施工时又不可...
In the design of underground parking lot, due to many factors, it is often encountered that the corner of the intersection should be arranged in a small size (less than about 40 °). Due to the small corner of the intersection, there are two technical parameters (Lx, δ in Figure 1) formula for the construction drawings at the point of intersection in the “Mining Design Manual” is not given, and the two technical parameters Closed at the bottom of the yard check and construction can not be ...
