Applications of SMW Method in Deep Pit Protection Engineering Under Complex Conditions

With engineering project examples, the paper has studied the SMW method in a complex environment of deep pit engineering and its effects in detail, which relates to the design of building envelope, construction requirements of building envelope and on-site monitoring, etc. Practice has proved that the method is economical and security. And it is one of the effective ways if the deep of project's pit is more than 10 meters.
