With the development of engineering construction, most of project layouts need to consider the time effect of structure deformation. For an idealized elastic mass, similarity conditions for time has been established for a long time. All of the actual materials have viscosity. However, considering the viscosity of materials and exerting load to make model test with centrifuge, similarity theory for simulating time has not yet been established. This paper makes a study of this problem and puts forward the similarity...

With the development of engineering construction, most of project layouts need to consider the time effect of structure deformation. For an idealized elastic mass, similarity conditions for time has been established for a long time. All of the actual materials have viscosity. However, considering the viscosity of materials and exerting load to make model test with centrifuge, similarity theory for simulating time has not yet been established. This paper makes a study of this problem and puts forward the similarity conditions which should be respectively met in making dynamic test and exerting load to study time effect with centrifuge in consideration of material viscosity.

工程建设的发展,不少工程问题需要考虑物体变形的时间效应。对于理想弹性体来说,时间相似条件早已明确。实际材料都是具有粘性的。考虑材料的粘性,并用离心机进行加荷来作模型试验,在模拟时间的相似理论方面似乎还有值得讨论的地方。本文对这一问题进行了研究,并提出了考虑材料的粘性时,作动力试验和用离心机加荷研究时效分别应满足的相似条件。

It is proved that the head waves are of nonlinear effects of the elastic wave equations. The analytic expressions of the equations are obtained under the condition that the media inside and outside a borehole are perfect elastic. It is illustrated that head waves are of a resonant mode and have no axial geometrical attenuation and that geomitical acoustics is not applicable to well logging and that the concept of "critical refracted arrival" is fictitious.

本文探讨了有机硅建筑密封剂潮气固化和降解的机理,并根据理想弹性体概念和理想弹性方程及Maxwel模型建立了有机硅建筑密封剂在潮气中曝露时交联和降解的动力学模型。通过实验数据求得了动力学方程。结果表明,有机硅建筑密封剂在潮气中的性能变化呈现两个不可逆的简单的一级反应,即交联反应和降解反应,这两个反应的速度常数分别为k1=0.0224(1/天)和k2=0.027(1/天)。本方程的建立,为有机硅建筑密封剂实际应用中寿命的预测有重要借鉴意义。
