Methods Of Control

Characterization of geotechnical digging and control the dynamical settlement is very necessary to mitigate construction risk. The metro tunnels of being constructed access to each other or near to the ground is high risk and physically difficult and costly. The control method becomes imperative. Some cases of digging prediction of ground movements and assessment of risk of damage to above or adjacent constructions have become an important issue especially in urban projec. Ground adaptability characterization is the key of control the tunneling in complex geotechnical conditions both in rock and soft stratum. High and changed water-soil pressure also is risk factors to effect tunneling process. Beside discussion of risk mitigation associate to tunnel construction, the developing settlement control and simulations are given to describe the methods of control risk.

According to the pharmaceutical industry produce VOCs and stench of atmospheric environment pollution, combined with typical pharmaceutical biological fermentation and chemical synthesis process of VOCs and odour pollution are classified 4 types:fermentation tail gas, recycling of exhaust gas, exhaust gas and wastewater workshop stench. The control technology should be selected according to the four types of waste characteristics.
