China University of Mining & Technology (Beijing) School of Mechanics and Civil Engineering，Beijing 100083；) Keywords: deep;Geotechnical mineral;soft rock types;deformation mechanical mechanism Abstract: As soft rock roadway projects have the characteristics of large deformation, and earth pressure,difficult to support, and all that make shallow form of support can not meet the needs of the soft rock roadway, the main reason is that the soft rock roadway has compound deformation mechanism, which makes that the single support physical science features and rock mechanical properties can not be coupled, and a key part of the soft rock roadway begins to undermine firstly, which leads to the instability of the entire supportive system.
Based on this transformation ideas, roadway supporting design has been successfully applied to engineering practice, which has a good effect.

Elasto-plastic Analysis Method for Vertically Loaded Pile Considering Pile-soil Slip Wenjuan Yao1,a, Shangping Chen1,b and Shengqing Zhu2,c 1Department of Civil Engineering, Shanghai University, Shanghai 200072, China 2Division of Aerospace Engineering, Nanyang Technological University, Singapore 639798 awjyao@shu.edu.cn, bshangping_chen@shu.edu.cn, czsq-w@163.com Keywords: Mindlin's solution, Relative displacement between pile and soil, Hyperbolic function, Slip Abstract.
The calculation and analysis of single pile settlement was one of the important geotechnical engineering issues, and many geotechnical engineers and scholars investigated and formed a systematic analysis method.
Introduction Currently, the analysis method of pile subjected to the vertical concentrated loads had formed a relatively systematic and theoretical approach [1-4], that is: load transfer method, shear displacement method, elasticity theory calculation method, finite element method, and the other empirical methods which were based on engineering practice.
An industrial plant in actual engineering, the cast-in place piles is used in pile foundation, and the diameters of pile is1000mm.
The soil modulus is taken as 3.5 from engineering experience in shanghai.

Particular Aspects Regarding the Radiative Heat Transfer in Thermal Analysis of Steel-Concrete Composite Structural Elements Lajos Imre1,a*, Cosmin Chiorean1,b 1Faculty of Civil Engineering, Technical University of Cluj-Napoca, 15 C.
In the case of a civil structure, the beam-type structural elements of the superstructure, have the purpose of ensuring the structural integrity of the assembly under different load intensities.
In the case of a civil structure thermal loads are generated form fire exposure, one of the most severe exposure conditions of a structural element during the service period.
Conclusions: Based on Fig. 3 the approximation of the soot absorption coefficient through a polynomial function of degree 2, presents a maximum deviation from the analytical curve of 5 %, for temperatures above 550 K, a deviation which is acceptable in civil engineering calculation.

Compare the results of optimization with the mix proportion in practice engineering case, we can reach the conclusion that Genetic Algorithm could reduce the cost, save energy, provides better use value on engineering practice.
The mathematical model for Optimized Design of High-Performance Concrete mixture ratio To optimize mix ratio of High-Performance Concrete, it should choose different optimization target according to the different requirement in specific engineering practice.
According to this optimization result, through appropriate adjustment, it will reach the mix proportion of concrete required in engineering practice.
