For the sake of safety and economy,the distance between SMW piles is optimized and reasonable design proposal is obtained.

Successive researchers have built many chemical equilibrium models such as HM model, HMW model and SMW model.

The application of SMW construction method in deep foundation for a certain drinking-water directly project from Hangzhou;

Application of SMW construction method to foundation reinforcement during cutter-changing of shield machine under normal pressure in construction of Yellow River Crossing of South-to-North Water Transfer Project

The SMW construction method application in foundation ditch maintenance engineering of Qinfen road in Wenzhou

On the construction technique of SMW method;

The application of SMW method in foundation pit support under complicated environment;

Using the SMW Method in a Pipe Project;

The study of characters of cemented soil in medium-hard soil by triaxial compression test of SMW for a foundation pit in Beijing subway have done,the results compare with SMW technology in soft-strata shown as follow:the cohesion in cemented soil was strengthened;the variation of internal friction angle in cemented soil is complex;the shea.

Through optimizing design, the supporting structure in the foundation pit uses the SMW technology of continuous wall plus inner-supporting system.

<abstract>is paper introduce the application of SMW technology to structure the protection of foundation excavation at south prolongation in the first line of Nanjing Metro.
