The reliability index is an important reliability parameter that is necessary for the development of reliability-based geotechnical design. Both the factor of safety (FS) and the reliability index (β) represent safety margin of structures against either failure or limit state. In this study, the reliability index is analyzed and evaluated in reference to the factor of safety currently adopted i...

Pile heat exchangers – where heat transfer pipes are cast into the building piled foundations – offer an opportunity to use ground energy systems without the additional construction costs related to the provision of special purpose heat exchangers. However, analysis methods for pile heat exchangers are still under development. In particular there is an absence of available methods and guidance ...

cover type of on–farm storages has an important role in reducing the freezing damage and respiration of beet roots in the pile. this experiment was conducted in 2006 in karaj region in order to evaluate the effects of cover types of storage on the mass and sugar losses of both topped and untopped beets. the experimental design was a split plot factorial in rcbd with three replications. the main...

The problem of soil±pile±foundation±superstructure interaction is examined, and a simple rational procedure to analyse the response of a structure supported on pile groups is presented. This procedure combines theories for the computation of the dynamic impedances and kinematic±seismic response factors of pile foundations with a multi-degree-of-freedom structural model. The procedure is applied...

A landslide located in northern Sichuan Province, China was investigated. series of numerical models the stabilized with piles and anchor cable frame beams were developed using a three-dimensional finite-element method. The Strength Reduction Method employed to investigate stability slopes, internal forces piles, axial cables. parametric study consisting pile position, length, spacing carried o...

We consider a modified Bouchaud-Cates-Ravi Prakash-Edwards model for pile surface dynamics, and show that in the long-scale limit this model converges to a quasistationary model of pile growth in the form of an evolutionary variational inequality.

In order to understand the load sharing and settlement reduction behaviour of piled raft resting on soft clay, 1g model tests were conducted on small-scale models. The parameters studied were the effect of pile length and number of piles. The load settlement behaviour obtained from the tests has been validated using simplified method (Polous & Davis). Equivalent pier concept of Poulos and Davis...

We introduce the algorithms for basis and decoding of quaternary lexicographic codes with minimum distance d = 3 for an arbitrary length n. 1. Introduction. In this section, we define some particular operations and discuss q-ary lexicographic codes with minimum distance d. The game-theoretic operations of nim-addition ⊕ and nim-multiplication ⊗ which are used in the Game of Nim are introduced b...
