Based on the examples of blasting excavation of the furrow for sound optical cablein 9 km highway side ditch, the authors put forward proposals and ideas about the determination of blasting parameters so as to offer references for similar engineering.

This paper introduces the actualities of communication of freeway roadside and points out the problems.

Stabilizing side slope of highway by using Vetiveria zizanionides technique had obvious economic and ecological benefits that its afforestation cover rate reached 90%, but the cost correspond from one fifth to one tenth of engineering measure.

In accordance with the high level of water and soil losses in the period of construction of high way,the soft way for stabilizing the slope of highway is necessary and some benefit and shortage was analysed,the right way of Vetiver grass technology for stabilizing slope of highway was confirmed.

A preliminary study on diurnal variation of carbonyl compound concentrations at roadside air of urban Guangzhou was performed in summer 2001.

Mechanism of biotechnichal protection for highway slope;

Analysis of regular framed anchor structures in highway slope protection;

The appliance of upper bound limit analysis to highway slope stability;
