Marquees are temporary light structures that are connected to the ground by tensile anchors to resist forces imposed by wind acting on the structure. Failures of such structures are not rare and have resulted in deaths and tens of thousands of dollars of damage. Consequently, an accurate estimation of the ultimate pullout capacity of ground anchors is essential; however, current methods for est...

The anchor pile is widely used in marine aquaculture, and its uplift resistance capacity determines the safety performance of aquaculture structure. Cyclic loads such as wind, waves, currents environment affect piles. By carrying out a cyclic loading model test piles for influence amplitude, initial tension angle, other factors on was investigated. experimental results showed that with an incre...

In this paper we introduce the Bidimensional Sand Pile Model (BSPM), that is, a generalization of the Sand Pile Model (SPM) with the addition of a further dimension. The SPM and some related models have been studied in many different domains and they play an important role in the theory of discrete dynamical systems. They were considered in the context of integer lattices by Brylawski in 1973. ...

To make the bearing capacity tests safer and more affordable for prestressed high-strength concrete (PHC) piles, this paper proposes a reaction device anchor piles filled with core grout based on geometric mechanical characteristics of PHC piles. The proposed has advantages convenient construction, strong controllability connection quality low cost. In addition, pile will not experience prestre...

In this paper, numerical analysis of a pile-soil interaction problem is presented considering the parameters influencing the axial load-deformation behavior of the pile embedded in a layered soil medium. The analysis is demonstrated with parametric solutions of a pile with underlain model soil strata under the axial force. An attempt is made to ascertain the extent of influence of elastic prope...

Using a series of model tests, this study investigated the effect of a passive pile on 3D ground deformation around a laterally loaded pile and on that laterally loaded pile's response in sand. The active pile head was subjected to lateral loads, and the passive pile was arranged in front of the active pile. In the model tests, the distance between the two pile centers was set to zero (i.e., a ...

Compared with conventional piles such as the circle pile, the cast-in-place large-diameter pile (PCC pile) has many advantages: the lateral area of PCC pile is larger and the bearing capacity of PCC pile is higher. It is more cost-effective than other piles such as square pile under the same condition. The deformation of the PCC pile is very important for its application. In order to obtain the...
