The structure and permeability of cover concrete, as well as the in-situ test method for testing the permeability of cover concrete are researched.

Problem and countermeasure of the field detection of the pile integrity by using the low strain method;

According to the experience of the field detection,this paper analyzes on the problems existing in the field detection of the depth of the protective layer of the structural solid reinforcement,and in the light of these problems,advances some measures that should be adopted.

In order to evaluate the energy saving performance of building envelope constructions and provide basis for analyses of operating energy consumption of buildings,the equipment of field test should be retrofitted,and much more thermal parameters should be measured.

The article introduced a kind of real time self suit Non-feedback auto-zero-adjustment circuts of which is used to field test and data collect .

Recently,the field test of energy conservation in building becomes a focus and crux in the building thermal engineering and HVAC field in China.

The field inspection of the instrument transformer and some points must be noticed.

The article sums up the application conditions of TLA mixed asphalt mixture in the Renmin Road Rebuilding Project in Zhuhai City,puts forward some points for attention in its spreading technology in order to ensure the engineering quality,and puts forward some requirements for its construction joint treatment,the field inspection and the quality control.
