The focus is paid on the study of build- ing height index which involves two aspects: one is the establishment of the detailed criteria of building height index based on classification of building height and different grades of control; the other is the con- crete basis of classification and the administration.

The control target of settlement according to.

But basic parameter and target of EVC need to be better,in the text,ACWP is partly improved,control target is developed,influence on wastage and price of material for engineering project cost is showed exactly,which made foundation for value and control the whole construction correctly.

After comparing experimented research with theoretical research and considering overseas pavement structure design method,proposal is made that the deflection should not be used any more as the design control target in the structural design of the bituminous pavement with flexible base,simultaneously put forward several proposals to this road structural design.

In this paper, the current research situation of the problems related to eco-environmental control index ofgroundwater had been expoundedsynthetically.

Based on the five sensitive experiment study, the injected water source of He 86 biolithite reservoir is assessed by means of scaling tendency calculation and lab flow test; injected water quality control index is studied by means of membrane filtration test, core jam test and bacterial plugging test.

During Yangshan Deepwater Port engineering construction, due to reasonable determination of concrete quality control indices, selection of construction technology, and final quality inspection,high performance of engineering concrete is ensured.

According to the requirements for the normal operation of the existing metro line,the control indices of settlements for station structure were put forward.

Study on kinetics flocculation mechanism and controlling index of high turbidity water;

Study on kinetics mechanism of mixing and controlling index;
