Project Introduction:

Focusing on the design standards of vehicle pit roadbed engineering of several urban rail transit, a full set of methods and treatment standards for functional zoning of foundation treatment of vehicle bases have been created by combining functional demands, bearing capacity characteristics and settlement requirements. The complete set of results has become the technical standards for foundation treatment of field sections of subways in many cities in China, and has also been written into a number of technical specifications; in view of the technical methods of vertical support under the special conditions of site constraints, the company has pioneered a variety of double-row support structure improvement measures combined with the needs of the actual project, and has conquered the key technology of double-row support system for vehicle bases of urban rail transit. Relying on the advanced technology, the company has participated in the design of more than 40 field section roadbeds all over the country, which includes the design of roadbed structure, foundation treatment, slope support, field section pit support and other design work.

Technical highlights:

1. Functional zoning method of site foundation treatment and treatment standard system oriented to technical standardization.

2. key technology of double-row support structure system for urban rail transit vehicle base
