چکیده
The deformation control effect of loess tunnel composite foundation plays an important role in optimization design and reinforcement evaluation. Systematically evaluate the adaptability jet grouting pile shallow collapsible tunnel. Taking buried section Fujiyao Tunnel with a depth 20 m as example, using MIDAS finite element numerical simulation software, during construction settlement after are systematically studied, differential is analyzed, bottom evaluated. results show that uplift displacement can be controlled by changing length increasing replacement ratio. combination long short piles significantly reduce uneven plastic zone foundation. 9 mm used evaluation index

متن کاملEvaluation of Composite Vane Materials for Rotary Sliding Vane Compressors
The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...

متن کاملEffects of Site Factors on the Performance of Rigid-Pile Composite Foundation in Tall Buildings
Values of site factors in numerical simulation can have profound effects on the calculation accuracy. In order to fully understand the performance of rigid-pile composite foundation in tall buildings, this article set up an overall FEA model of a 25-storey frame-tube structure by considering the interaction of superstructure, foundation and ground. Thereafter, a detailed parametric study was pe...
متن کاملRelevance vector machine and multivariate adaptive regression spline for modelling ultimate capacity of pile foundation
This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...
