Load Capacity of Type 321 Bailey Bridge
Type 321 Bailey Bridge is a prefabricated steel bridge widely used in various engineering scenarios, with high load capacity and fast construction. The following is the specific load capacity of Type 321 Bailey Bridge:
1. **Design Load**
Type 321 Bailey Bridge is suitable for a variety of load levels, as follows:
- **Automobile Load**: Applicable to Auto-10, Auto-15, Auto-20.
- **Track Load**: Able to carry crawler load of 50 tons.
- **Trailer Load**: Able to carry trailer-80.
2. **Specific Parameters**
- **Single-piece Bailey Beam**:
- Allowable bending moment (MX): 782 kN-m.
- Allowable shear force (QX): 242 kN.
- **Combined bridge**:
- Single-layer single row (SS): allowable bending moment 78.82 T.m, allowable shear force 24.52 T.
- Double-layer double row (DS): allowable bending moment 157.64 T.m, allowable shear force 49.04 T.
- Three-row single layer (TS): allowable bending moment 224.637 T.m, allowable shear force 69.882 T.
- Double-row double layer (DD): allowable bending moment 326.54 T.m, allowable shear force 49.05 T.
- Three-row double layer (TD): allowable bending moment 465.32 T.m, allowable shear force 69.89 T.
3. **Actual application case**
In actual application, the 321 type Bailey bridge can meet the traffic needs of various heavy vehicles. For example, in a certain project, 321-type Bailey bridges were used as the main beams, with a 6-row single-layer top-bearing structure and a designed traffic load of 100 tons.
Summary
The 321-type Bailey bridge can meet the traffic needs of a variety of heavy vehicles due to its high load-bearing capacity, rapid assembly and disassembly, and strong adaptability. Its design loads include car-10, car-15, car-20, crawler-50, and trailer-80, making it an ideal choice for various complex engineering needs.
