In order to find a more effective intelligent method for truss optimization, we proposed an improved bat algorithm and introduced it into truss optimization. The initial population was optimized by using the good point set weighted approach in bat optimization formula. Individuals with high fitness were retained and individuals with low fitness wer...

The ground support system has a significant impact on tunnel safety while the installation time of initial support is commonly designed by empirical method. The three dimensional numerical model, based on the engineering practice, is analyzed by FLAC3D. In this paper, an improved LDP (longitudinal displacement profile) equation is proposed, which i...

This paper aims to assess the face stability for tunnels excavated in weathered and saturated rock masses using the Hoek-Brown failure criterion. With resort to the upper bound theorem of limit analysis, a 3D rotational failure mechanism is constructed in which the rate of work done by pore water pressure is calculated as a part of external work by...

With the advantage of superior crack width control ability, stress transmission capacity and energy dissipation capacity, engineered cementitious composites (ECC) show ultra-high strain hardening characteristic, and its ultimate tensile strain can reach 3% to 7%, which is hundreds of times that of the normal concrete when cracking occurs. As a new ...

The identification of structural plane connectivity is an application problem in rock mass engineering. Theoretically, information of exposed rock mass and its internal borehole is of great significance to predict network of unexcavated rock structural plane, especially in tunnel engineering. In this paper, parameters of structural planes have been...

Chemical grouting has been widely used to ensure the stability and durability of built structures by enhancing the engineering properties of soils. The objective of this study was to investigate the effect of a newly developed acrylate-cement grout, composed of component A (acrylic polymer, catalyst, and hardener) and component B (cement) having mi...
