理论弯沉值的计算及施工弯沉检验标准

路基、路面回弹模量是设计和施工的重要指标,但回弹模量是变化的线性函数,较难直接测量,在施工中采用了路基弯沉测量来间接控制回弹模量。用多层弹性体系理论方法全方位阐述路基路面各层回弹模量与总弯沉值的关系,给出施工过程中控制弯沉值的理论标准。用此方法计算理论弯沉值可以在实际施工中及时了解路基质量情况。

The calculation of theoretic rebound deflection and test standard of deflection in construction

Resilience modulus of pavement and roadbed are important indexes of design and construction, but we usually master the resilience modulus indirectly by the roadbed flexure measuring,because the modulus of resilience is linear function and it's too difficult to measure it directly. the paper expoundes the relationship between the resilience modulus of roadbed and pavement each layer and the whole modulus of resilience entirely by using the ways multilayer resilience system theory illustrated, and gives the theoretic standard of resilience modulus of control during the construction. The most distinct advantage of calculating the theoretic modulus of resilience by adopting the calculation method is that we could take all situation of roadbed quality under control.
