Engineering Geologic Condition in Karst Area Strata in karst area are as following.
Engineering Characters of Pile Foundation in Karst Area In karst area, there exists considerable difficulties in pile foundation operation process and it’s possible that serious hidden quality problem may occur.
If settled material is too thick, engineering pile safety cannot be guaranteed.
For example, to calculate engineering pile length according to presumed wave speed and transmission time of concrete.

Study on the Evaluation Method of Engineering General Contracting Enterprises Multi-project Selection Xinhua Wu1,a, Na Tang2,b, Fengzhen Liu1,c 1Department of Resource and civil engineering, Shandong University of Science and Technology, Taian, Shandong province, 271019,China 2 Graduate School of SDUST, Shandong University of Science and Technology, Tsingtao, Shandong province, 266590,China axinhuawu@126.com, btangna2012@126.com, clfz828@126.com Keywords: Engineering General Contractor,Multi-Project Management,Evaluation Index System, Multi-Level Gray Relational Analysis.
The purpose of this study is to provide an ideal multi-project selection method.The influence factors of the contractors project selection are analyzed according to the characteristics of engineering general contracting enterprises(EGCE) multi-project management.The evaluation index system of EGCE multi-project selection is build by expert advice and the method of research papers retrieved.The index system is divided into 4 levels, and includes 27 indicators in six areas.A based on multi-level gray relational analysis comprehensive evaluation model is proposed to evaluate the priority of the projects.The evaluation method may help EGCE choose the projects to meet their own development strategies.
Introduction Engineering general contract(EGC), with the development of economic and social and the owners of the comprehensive and integrated service needs is getting higher and higher, in the long-term development process of the construction industry,has been become a reality .In general, EGC should include the whole process of survey,design, procurement, construction and commissioning of the project or several stages of the contracting[1].

The characteristics of expansive soil have terrible influence on engineering structure.
Therefore, the research on the engineering properties of expansive soil is related to the slope stability and the safety of the buildings.
In order to save the construction period, water drilling construction was adopted without free section, as a result, partial collapse occurred before the construction of overall slope was completed, the maximum displacement in the place without collapse reached 120mm and cracks of different degrees occurred to many civil buildings in the west.

The Engine life prediction using take-off EGT Margin Currently, on condition maintenance is widely used for civil aviation Engine.
In Engineering, usually take-off EGTM is directly used to predict the Engine remaining life, to be outlined below.
Here we have analyzed and discussed the civil aviation Engine life prediction based on take-off EGT Margin.
