The development of cooperative relationships among project participants makes relationship norms an important governance mechanism to promote behavior. However, the research on mostly ignored network environment established by participants. A static cannot accurately reflect actual state from perspective embeddedness, but behavior dynamic embeddedness is limited. Therefore, this study overcame limitation analysis. This paper divided implementation process construction projects into early,...
Experimental measurements in our present diode-laser-pumped Rb buffer-gas-cell frequency standard show that the sensitivity to microwave PM noise is approximately a factor of 10 lower when square-wave modulation used place more traditional sine-wave modulation. This result virtually eliminates what had been serious limitation stability attainable cell-type standards. It also has ramifications for low-cost, commercial
According to non-equilibrium evolution stability and control theory, over force is the internal effective driving of unrecoverable time-dependent deformation. The distribution reflects failure position mode tunnel. opposite optimal reinforcement prevent deformation provides a quantitative accurate design method for plastic complementary energy (PCE) norm force. curve PCE versus time unified criterion real dynamic evaluation tunnel in process under various external disturbing factors. Based...
ABSTRACT Aiming at the problem of high geostress faced by deep buried tunnel, mechanical characteristics and optimization composite lining structure are studied. The influence consolidation grouting ring backfill measures on studied based three-dimensional finite element calculation theory, so as to determine optimal thickness concrete lining. maximum tensile stress 20cm during operation is about 8.73MPa, that 120cm 4.68MPa. pressure construction period −13.47MPa, −4.95MPa. After...
ABSTRACT: Aiming at the problem of high external water pressure in deep buried tunnel, maximum concrete lining caused by seepage field surrounding rock is numerically studied, and influence consolidation grouting ring drainage measures studied based on stable analysis. When holes are arranged underground level around tunnel funnel-shaped its line affected to some extent. The surface location about 100m lower than original level. head outside ring, shotcrete secondary 490m, 260m 255m,...
