The high pseudo-ductility of Engineered Cementitious Composites (ECC) makes it a particularly effective material to resist the propagation of cracks.
Introduction Recent advances in micromechanics and material processing techniques have made possible the development of engineered cementitious composites (ECC) that exhibit pseudo-ductile behavior under tensile loading [1].
In engineering applications, ECC components show excellent strength and ductility under shear, impact and localized tensile stresses.

Back Analysis of Initial Stress and Mechanical Parameters in Deep Buried Highway Tunnel Xiang-hui Deng College of Civil and Architecture Engineering, Xi’an Technological University, Xi’an 710032, China dh_gl@163.com Key words: Back analysis, Initial stress, Mechanical parameters, Deep buried tunnel Abstract.
Thus, for satisfying engineering design and construction, it is necessary to back analyze the in-situ stress.
Introduction Initial stress is the primary acting force that leads to deformation and failure of geotechnical engineering such as tunnel of transportation, underground mining, and electric power engineering.
Most engineers are inclined to know the in situ stress before their design.
