- 摘要：In light of the planning of General Mountain Park in Zhangzhou and its execution, this paper intends to explore the relationship of spatial structure between the historical birthplace of Zhangzhou exploitation at the beginning of Tang Dynasty and the place where the first ancestors of Zhangzhou exploitation were buried. This paper then presents the artistic techniques and features of the spaces in General Mountain Park in respect of geography, planning structure and traditional courtyard. Thus, the conclusion is drawn in this paper that by means of the combination of modernity with tradition as well as the history with the realism, the spatial art is supposed to establish the Chinese traditional construction culture characterized by nationality and locality.718|6|0更新时间：2023-11-28

- 摘要：In millisecond blast engineering,the key to achieving millisecond blast is to ascertain reasonable delay time interval.Firstly,the authors make use of time-energy density analysis based on wavelet transform,and get the real delay time by identifying the blast moment of short-delay detonators.Secondly,every sub-signal is separated from measured millisecond blast vibration signal by time-frequency domain transform techniques.Lastly,the Optimized delay time interval is obtained by comparing the superposition effect of sub-signal in different delay time interval.The effectiveness of the proposed method is verified with time-energy density analysis of millisecond blasting vibration signals in an underground project.It shows a high theoretical and practical value,and establishes a theoretical and technical foundation for the study of controlling and forecasting blast vibration damage.598|6|0更新时间：2023-11-28

- 摘要：Using WAW-2000 a multifunction servo-controlled testing machine,uniaxial quasi-static compression experiments for the steel fiber reinforced concrete(SFRC) were conducted with three strain rates.The volume fraction(V_f)of SFRC ranged from 0% to 3%,and the matrix was C50 concrete.The whole stress-strain curves of matrix and SFRC were obtained,and the results showed that with the increase of V_f,the compressive strength increased slowly,while the toughness increase quickly.With the increase of the strain rate,the strength of SFRC increased,but the toughness decreased,and the more the Vf,the less decreasing of the toughness.The results also showed that the elastic modulus and Poisson's ratio of SFRC were not sensitive material parameters,and with the increase of V_f,the former raised slightly and the latter decreased a little,respectively.A well suited numerical expression of the compressive stress-strain curve applicable to SFRC was put forward.646|709|0更新时间：2023-11-28
- 摘要：According to the strain nonlinear softening constitutive model having inflexion point after peak stress of practical rock and considering intermediate principal stress, the plastic zone of circular cavern with liner under the condition of uniform pressure is analyzed. The elasto - plastic boundaries both for the lining and surrounding rock are discussed. The stress distribution law is different due to the different position of elastic - plastic boundary. Based on this, different stress formulas are gained. The critical pressure caused by excavation of cavern leading to the yield zone and that caused by inner pressure leading to the yield of the liner and surrounding rock is introduced.567|692|0更新时间：2023-11-28
- 摘要：The shear lag effect in frame-tube structures can be neglected when the ratio of beam's span to height increases to some degree,and its behaviors comes close to the behaviors of frame structures.The maximum ratio of beam's span to height is obtained by the equal side-sway of two structures.The structure should belong to frame structures when its ratio of beam's span to height exceeds the critical value.Otherwise,it should belong to frame-tube structures.According to the analysis of the various parameters,some influence factors can be obtained,and the process to distinguish the two structural systems is given.It is shown that this method is accurate and convenient enough for use during the preliminary stage of design.634|961|0更新时间：2023-11-28
