Underground engineering (selected articles)
Abstract
Statistical analysis is used to evaluate the strength of underground injected concrete structures. The objective was to explore a method to test the strength at an early stage. Empirical formulas were derived to correlate the strength measured in an early stage to that of a later stage. Also, the repair and reinforcement of underground structures is discussed. Methods for finding the causes of cracks and deformation are given, as well as procedures for repair.
