Loess is a kind of special sediment with pore structure and rich carbonate in its composition. Due to the characteristics composition, most loess has collapsibility. There are resources distributed northwest area China. With improvement traffic network west area, use as roadbed gradually increasing. Therefore, during construction process, engineering problems encountered by also increased, whic...

The pile’s ultimate capacity or failure load must be computed by some criteria using load-settlement curve data gathered during the pile test. Many scholars have proposed several approaches for evaluating in past. This study compared different to predict piles with two lengths-to-diameter ratios embedded gypseous soil gypsum content of 60% under soaked and unsoaked conditions. Two types were us...

A graph is called biclaw-free if it has no biclaw as an induced subgraph. In this note, we prove that if G is a connected bipartite biclaw-free graph with δ(G) ≥ 5, then G is collapsible, and of course supereulerian. This bound is best possible.

In this paper, we investigate unsteady behavior of flexible vessels carrying a blood flow. Membrane model with constant tension for the vessel walls and incompressible newtonian fluid approximation for blood is adopted. Developed computational model is applied to simulate the coupled fluid-wall behavior in 2D collapsible channels and 3D collapsible tubes. INTRODUCTION Vessels carrying blood flo...

This study looks into the influence of matric suction on volume change gypsum sand soil in unsaturated conditions. The specimens were collected from Al-Najaf, Iraq, and included 14 29% gypsum. Three series initial stress laboratory tests utilized a modified oedometer device. For each content, twelve remolded examined circumstances with applied using four matrices (30 kPa, 18 9 saturated state)....

We prove a sufficient condition for finite clique complex to collapse k-dimensional complex, and use this exhibit thresholds (k+1)-collapsibility in sparse random complex. In particular, if every strongly connected, pure (k+1)-dimensional subcomplex of X has vertex degree at most 2k+1, then is (k+1)-collapsible. the model X(n,p) complexes an Erdős–Rényi graph G(n,p), we show that any fixed k≥0,...

Abstract In order to meet environmental and socio-economic challenges, the recycling of waste be used in treatment geotechnical problems is one main ways preserving environment with a lower economic value. The objective this experimental work improve characteristics study mechanical behaviour collapsible soil treated new hydraulic stabilizer composed Crushed Granulated Blast Furnace Slag (CGBS)...
