Testing Study on Ratio of Crack Widths on Two Sides of Protective Covering of Steel-Lined Reinforced Concrete Penstock
According to mechanic properties of steel-lined reinforced concrete penstock, author abstracted and simplified its mechanical model, designed and produced 20 axis tensile structures of reinforced concrete, and proposed the test methods on the ratio of crack widths on two sides of concrete protective covering. The measured results are consistent with the calculation results of empirical formula, which on one hand shows the test scheme is feasible, on the other hand verifies the rationality of empirical formula, and it has important significance for perfecting the theory and application of steel-lined reinforced concrete penstock.
