Engineering geological problems caused by city planning and its management countermeasure

Geological environment condition is the basic factor for city existence and stability and the foundation for city construction. In city construction belts with comparably stable earth crust and good geological environment is preferable. Hence, engineering geological condition must be taken into consideration during urban construction. And city is a place where the geological environment is much influenced by human activities whose forming type, function, land used and development have a close relationship with geological environment. To survive and get maximum benefit, human make the best of environment to construct in many ways. Nowadays city planning and construction is developed from simplex plane style to the dimensional style. Increase of high-rising, unceasing construction of substructure work, development of higher, deeper, longer, larger, heavier, clustered urban construction arouse engineering geological problems brought by city construction. Characteristic of city construction is that it comes along with city and its harmfulness increases with city development. Yet an effective management way is to keep to the conception that human and geological environment should be in harmony among planning, construction and geological environment.
