## 1. What factors should be considered when choosing tunnel housing formwork?

When choosing tunnel housing formwork, it is important to consider factors such as the size and shape of the tunnel, the soil conditions, the expected loads on the formwork, and the construction schedule. The formwork should be designed to withstand the pressure exerted by the surrounding soil and the weight of the tunnel lining, while also providing a smooth surface for the concrete to be poured against. Additionally, the formwork should be easy to install and dismantle, as well as durable enough to withstand multiple uses.

## 2. How can the durability of tunnel housing formwork be assessed?

The durability of tunnel housing formwork can be assessed by considering the material it is made of, the quality of construction, and the maintenance practices followed. Materials such as steel, aluminum, and timber are commonly used for tunnel housing formwork, with each having its own advantages and disadvantages in terms of durability. Steel formwork is known for its strength and long lifespan, while aluminum formwork offers a lightweight and corrosion-resistant option. Timber formwork may be suitable for temporary or small-scale projects, but may require more frequent maintenance and replacement.

## 3. What are some common materials used in tunnel housing formwork?

Common materials used in tunnel housing formwork include steel, aluminum, and timber. Steel formwork is often preferred for its strength, durability, and ability to be reused multiple times. Aluminum formwork is lightweight, corrosion-resistant, and easy to assemble and disassemble, making it a popular choice for tunnel construction projects. Timber formwork may be used for smaller tunnels or temporary structures, but may require more maintenance and have a shorter lifespan compared to steel and aluminum options. Choosing the right material for tunnel housing formwork will depend on factors such as the project requirements, budget, and expected lifespan of the formwork.
