对于抗压强度很高而抗拉、抗剪强度较低的岩体和混凝土建筑物,利用高强度钢丝束进行预应力锚固,可以使软弱结构面形成预压应力状态,大大提高软弱结构面的抗剪、抗拉和抗裂能力。理论分析和工程实践均已充分证明:工程中采用预应力锚固措施具有效果明显、经济合理、适应面广、抗震性强以及与其他结构干扰小等优点,而且既可用于新建工程中,也可以在已建工程运行中进行补强加固。
For rock and concrete structures with high compressive strength and low tensile strength and shear strength, prestressed anchoring with high-strength steel wire bundles can make pre-stressed state of weak structure surface and greatly improve the surface of weak structure surface Shear, tensile and crack resistance. Both theoretical analysis and engineering practice have fully proved that the prestressed anchorage measures in the project have the advantages of obvious effect, reasonable economy, wide adaptability, strong earthquake resistance and little interference with other structures, and can be used in new construction projects as well as Reinforced and reinforced in the operation of the built project.
