clear span 基本释义：
clear span在建筑学中指的是桥梁或构架的净跨度，即不考虑桥面、人行道、车行道等实际铺装层的宽度，仅考虑结构本身的跨径。
发音：/kl??/ sp?n/
英语范文：
The clear span of the bridge is an important factor in its design. It determines how wide the roadway needs to be, and thus how many vehicles it can accommodate.

题目：设计一个理想的桥梁结构
在现代桥梁设计中，选择合适的材料和结构是至关重要的。一个理想的桥梁结构应该具有足够的强度和稳定性，同时也要考虑到施工成本和时间。在选择桥梁结构时，净跨度是一个重要的考虑因素。
在理想的条件下，净跨度可以提供更大的空间，使得桥梁可以承载更多的重量和流量。然而，净跨度也受到许多因素的影响，如地形、气候、材料和施工方法等。因此，在设计桥梁时，我们需要仔细考虑这些因素，以确保桥梁的稳定性和安全性。
基于以上考虑，我建议使用高强度钢作为主要材料，因为它的强度和稳定性都非常好。同时，我们还需要考虑到施工时间和成本，因此需要选择合适的施工方法和技术。最后，我们需要考虑到桥梁的美观性和环保性，以确保它能够与周围环境和谐共存。
总之，在设计一个理想的桥梁结构时，我们需要综合考虑各种因素，包括净跨度、材料、施工方法、时间和成本等。只有这样，我们才能设计出一个既安全又美观的桥梁结构。

clear span
Clear span refers to the maximum length that a bridge can span without touching any obstacles on both sides. It is an important parameter of bridge design that determines the size and location of the bridge.
In terms of practical applications, clear span has a significant impact on the planning and construction of bridges. It determines whether a bridge can accommodate large vehicles or heavy loads, and whether it can be used for public transportation or freight transportation. Therefore, clear span must be carefully considered during the planning and design stages of bridge construction.
In terms of language structure, "clear" in this context means "without obstruction" or "free from interference." "Span" refers to the distance that a bridge extends over an obstacle or ground surface. Therefore, "clear span" means the maximum distance that a bridge can extend over an obstacle without touching it.
To illustrate this concept with an example, if a bridge is designed to span a river, the clear span will be the distance that the bridge extends over the river without touching any obstacles on the riverbed or banks. If the clear span is too short, the bridge may not be able to accommodate large vehicles or heavy loads, or it may not be suitable for public transportation.
In summary, "clear span" refers to the maximum distance that a bridge can extend over an obstacle without touching it, and it is an important parameter in bridge design that must be carefully considered during the planning and construction stages.
