写一篇地铁车站细部构造防水和柔性防水的作用为题的论文

地铁车站细部构造防水和柔性防水的作用 随着城市化的发展，地铁车站的构造正变得越来越复杂。为了保证地铁车站安全、美观、耐用，必须采取有效的防水措施。这就要求地下工程必须采用合理的防水方法，以保证它们能够正常运行。本文将对地下工程中使用的两种常见的防水方法——固体/传统/相对固体/不易弯曲/不易扩大的“固态”和“柔性”——进行详尽分析，以便于我们能够充分理解其应用于地下工程中时所发生的作用。 固态是一种传统形式上使用最广泛、效力最强大、加固效应最好的一种形式。它是一层厚厚耐久耐侯、不易裂口、不易扩大或弯曲变形的物料，如水泥浆料或特制填料，覆盖地表或者内部壁壳上。它能够很好地减少水浸入时泵出量，并保留大量零散零浸入量。然而，它也存在一些问题——它不能随时改变形态来应对各种情况；如遇到裂隙或者凹凸部位时会存在问题;也很难应对特别情况(如大风)时所带来的问题;也会难以看到内部情况;后期修补也十分困难…… 相对而论, 所谓"柔性" 针对上述问 题, 已 经 进 行 了 深 层 次 的 改 进 与 众 多 突 破, 加 州 太 高 等 有 机 材 料 已 被 多 次 地 骤 试 , 使 地 下 工 筑 能 处 高 高 抗 震 , 低 渗 , 有 机 - 绿 色 - 精 神 . "Rigid" materials such as cement mortar and special fillers can be used to cover the surface or inner shell of the station. This material can effectively reduce the pump-out amount when water seepage occurs and retain a large amount of scattered seepage. However, it also has some problems - it cannot change its shape at any time to cope with various situations; there will be problems when encountering cracks or bumps; it is also difficult to deal with special situations (such as strong winds); and it is also difficult to see the internal situation; later repair is also very difficult... Compared with this, the so-called "flexible" has undergone deep improvement and many breakthroughs in view of these problems. California high organic materials have been tested multiple times so that underground engineering can withstand high seismic resistance, low permeability and organic-green-spiritual. It has good toughness and flexibility during construction, which can effectively prevent cracking due to deformation caused by external forces such as earthquakes. At the same time, its elasticity allows it to adapt flexibly according to changes in temperature or humidity in order to maintain a certain degree of sealing effect. In addition, due to its non-toxic nature and environmental protection performance advantages compared with traditional rigid materials such as cement mortar or asphalt coating materials, flexible waterproofing materials are increasingly favored by people nowadays. In summary, both rigid and flexible waterproofing methods have their own advantages and disadvantages when applied in underground engineering projects. Therefore, engineers should choose different methods according to different conditions on site so as to ensure that the station can achieve optimal protection effect while ensuring safety performance at the same time.
