Degree Of Filling

<p>A new method has been developed for modeling acoustic monitoring of a layered-block elastic medium with several inclusions of various physical, mechanical and phase hierarchical structures. An iterative process is developed for solving the direct problem for the case of three hierarchical inclusions of l, m, s-th ranks based on the use of 2D integral-differential equations. The degree of hierarchy of inclusions is determined by the values ​​of their ranks, which can be different. Hierarchical inclusions are located in one layer: the first is anomalously dense, the second is anomalously plastic, and the third is anomalously elastic and fluid-saturated density. The degree of filling with inclusions of each rank for all three hierarchical inclusions is different. The simulation results can be used in monitoring studies of the control of fluid return from oil fields developed as part of horizontal drilling.</p><p> </p>

Creep And Shrinkage

The knowledge of the microstructure is a point of major importance to understand the transport, mechanics, creep and shrinkage properties. The present work proposes a method to quantitatively predict the volume percentage of each of phases in Portland cement pastes. The saturated density of C-S-H is revised as a function of degree of hydration and water to cement ratio (w/c). The computed results are consistent with experimental values for cement paste that performed in this study.

The change of Shanghai soft soil’s density with drainage time during foundation pit dewatering was investigated, through taking samples in each soil layer to be laboratory tested after the groundwater level of observation hole in project site had been lowered below the position soil sampled for at least 5 days. Experimental results show that groundwater included in drainage zone couldn’t be discharged immediately with the drop of groundwater table, which may be named as “lag draining” phenomenon; soil’s water-holding density can also be deduced from soil saturated density and specific field except directly measured from laboratory test. The effect of engineering pumping will reduce the discrete of soil density distribution; a centralized distribution of soil density emerges after dewatering.
