Geological Protection Project of the Longmen Grottoes in Luoyang Qi-xia Liu 1,2,a, Yong-hui Duan 1,2,b, and Jun-yan Deng 1,c 1School of Civil Engineering and Architecture, Wuhan University of Technology Hubei Wuhan China, 2Civil Engineering and Architecture College, Henan University of Technology Henan Zhengzhou China aliuqixia65@163.com, bzzrdfdc@163.com,c 903202329@qq.com Keywords: Stone cultural relic; Geological condition; Protection project..
According to engineering and hydro geological conditions of the Longmen Grottoes, we conducted a geological hazard investigation of 3 caverns ( Qianxi temple and HuangPuGong cave and Lu hole ), dividing the damage effects of Longmen Grottoes into mechanics effect, chemical effect and biology effect, and among the three, the damage caused by chemical effect is the most direct and obvious.
This is a major breakthrough in the cavern grouting field, and it also can be applied to other caverns protection engineering.

Metamaterials has more applications in engineering, communication, information and so on.
The control of heat flow is of great significance in both civil and military fields.
New physical discovery is undoubtedly necessary for all kinds of metamaterials, and the main and new task for metamaterials is engineering application.
More and more metamaterials with different functions are emerging and will continue to penetrate into practical applications and play an important role in engineering, environment, communication, information, military and other fields.

Some applications of fractal fracture mechanics to describe the fatigue behaviour of materials Andrea Carpinteri 1, a, Andrea Spagnoli 1, b and Sabrina Vantadori 1,c 1 Department of Civil Engineering, University of Parma, Viale G.P.
It is worth remarking that the horizontal asymptote for large structural sizes, which is of great engineering significance, is also predicted by scaling laws based on the stress gradient concept (for instance, see Ref.[26]).

Anaerobic digestion is a method engineered to decompose organic matter by a variety of anaerobic microorganisms under oxygen-free conditions.
The capital expenditure of the civil structures at the biogas plant is determined by means of the method of aggregated building work items (itemised budget), using a specialized software for budgeting building work BUILDpower by RTS corporation.

Technical and Contractual Trends for Micro Tunneling Projects in Romania and Bulgaria George Tsitsas1,a *, Chavdar Kolev2,b, Liliana Radoi3,c, Vlad Petrila4,d 1*GT Ground Engineering & Construction Services, Bucharest, Romania 2Associate Professor University of Transport Sofia, Bulgaria 3 Member of Bucharest Bar, Bucharest, Romania 4 GT Ground Engineering & Construction Services, Bucharest, Romania ageorge.tsitsas@gtengineering.ro, bch_kolev@abv.bg, cliliana@radoi.ro, dvlad.petrila@gtengineering.ro Keywords: Pipe-Jacking, Underground Works, Contracts, Risks Abstract.
Construction contracts in Romania including those for micro-tunneling projects are governed by the provisions of the New Civil Code that became a law in October 2011.
This allocation of risk can be promoted by an independent expert (engineer / project manager / consultant), certifying the correct execution of works, authorize payments, and supervise the fair conduct of both parties involved in the contract.
Project owners, engineers, and construction companies have to anticipate and prevent risks, justify their decisions for interventions and operations, control costs and deadlines, within the context of sustainable development.
