在有锚杆或基桩的底板温度应力计算中,锚杆(桩)对温度应力的影响尚无成熟的方法计算.本文在一定的假定下推导了锚杆(桩)的约束系数的计算式,并通过试验资料和工程实例作了验证,基本上可用于实际工程中的多排锚杆(桩)的约束系数及温度应力计算.此外,基本参数B中的锚杆(桩)抗力数R_x一般通过试验确定,也可用(25)式估算,其精度基本满足工程要求.
In the calculation of the floor temperature stress of anchor or pile, there is no mature method to calculate the influence of the anchor (pile) on the temperature stress.This paper derives the calculation formula of the restraint coefficient of the anchor (pile) under certain assumptions , And verified by the experimental data and engineering examples, which can be basically used to calculate the restraint coefficient and temperature stress of multi-row anchor (pile) in the actual project.In addition, the anchor bolt resistance R_x Generally determined by testing, but also can be used (25) Estimation, the accuracy of the basic project to meet the requirements.
