Exhaust steam pressure control of ACC,control steps of ACC fans and ACC anti-freezing protection in winter were emphatically elaborated to give certain reference to units using air cooling condenser.

According to environmental conditions of loess plateau in Luliang of Shanxi Province,the paper proposed some suggestions about plant protection and vegetation restoration for expressway slope,also discussed the basic principle of plant protection,methods for planting and water and soil conservation as well as plant cultivation.

Based on the principle of the slope plant protection and reaction way,with the help of the hydraulics and sediment corrosion theory and formula,calculation ways for the function effect of the slope plant protection are obtained,the canonical calculation way for the ability of the slope plant protection is inexistent.

Method of plant protecting in highway subgrade slope;

The slope soil after plant protecting is regarded as root-soil complex,the interactive mechanics model of root-soil is established,reinforeced effect of plant roots is quantitatively analysed to increase shear strength of the soil of the slope and decrease water loss and soil erosion,and all kinds of the slope diseases.

Single selection of protection plant on slope of Jinfu expressway;
