The research of tunnel monitoring technology applied in complicated underground geological conditions take their engineering characteristics into consideration.
Fig.3 The working drawing in the open section Research Plan 7381 tunnel project is located in the transformation period of roads, buildings on both sides of the road in the dense, if once accident ，consequences will be very serious.Due to the tunnel construction technology in the expansion project is not mature, in construction monitoring no ready experience, can only reference city tunnel project experience and according to characteristics of this project to work.According to the problems, in complex geological conditions and environment special 7381 tunnel civil air defence, it is necessary to transform period in combination with the engineering characteristics and construction measures for field monitoring.According to relevant standards in the building's settlement of respectively, surface subsidence, vaults settlement of surrounding rock, convergence monitoring work in table1.

Application Research of Orthogonal Analysis for Components Selection of Heat-resistant Concrete Xingwei Xu1,a, Ji Yao2,b 1Department of Civil Engineering in Kunming Metallurgy College, Kunming Yunnan, 650033; 2Faculty of Civil Engineering and Mechanics in Kunming University of Science and Technology, Kunming Yunnan, 650500 a 276308990@qq.com, b105434620@qq.com Keywords: heat-resistant concrete, orthogonal test, variance analysis, range analysis, components Abstract.Combined with the heat-resistant concrete needed for a company combustor, based on the availability of local raw materials, the orthogonal test was used, then by the variance analysis and range analysis, the components of the heat-resistant concrete which could meet the technical requirements of the project were selected.
Engineering application results showed: the components of the concrete could meet technical indicators for the engineering application, and effectively reduced the cost of production of heat-resistant concrete.
Project overview A combustor projects in an engineering required about 1500m3concrete of heat-resistant temperature of 800 ℃, the technical indicators required in construction are as follows: 1.
After the project put into use, the company conducted a routine monitoring of the combustion , so far, has not yet appeared obvious cracks in the combustion and other engineering quality problems.
