T/SCDA 090-2021 ZYZ pre-stressed concrete square pile by tension method
Basic Information
Scope
Main technical content: 1. The square piles in this collection are suitable for low-pile foundation applications in industrial and civil buildings, structures, and other projects with seismic fortification intensity of Grade 7 and Class C or Class B in China. They can also be used as reference for low-pile foundation projects in railway, highway, bridge, port, municipal, and water conservancy projects. 2. The square piles in this collection are designed for durability in Class IIB environments. When the foundation environment and geological conditions are erosive to the piles and the designed service life exceeds 50 years, reinforcing and anti-corrosion measures should be taken according to relevant standards based on the actual usage conditions. 3. The square piles in this collection are suitable for pile foundation projects subject to vertical compressive loads and vertical uplift loads. When used in pile foundation projects subject to large horizontal loads, special design and verification calculations should be conducted.
