Abstract: During last years the national economy is developed and grows by a rate of 10% per year. Thus we can predict with high growing development of our national economy,many large engineering projects, which could fall into the raw of largest ones in the world will be constructed in China in the 21st century. For this reason Chinese engineering geologists must take reasearch beforehand: earlier engineering geological indentification of the fearibility of sites for large projects, the engineering geological challenges and problems which could arise in the process of construction, the engineering geological prediction and prevention of environment after construction, in order to provide a sound basis for future design and construction of the large engineering projects.
