Study on Failure Mode of Underground Diaphragm Wall in Soft Soil Area

Abstract:

Zhejiang Province is Located in the Yangtze River Delta which the Soft Soil has Large Thickness and the High Underground Water Level.There is a Higher Requirement for the Optimization Design and Safety Construction of Deep Foundation.According to the Summary and Analysis of some Common Cause Failure of the Foundation Pit Engineering，we can Conclude that there are some Failure Mode in Soft Soil Area of Underground Diaphragm Wall Structure such as Foundation Pit System Instability，Basal Failure，Piping and the Flow of Sand Damage，Support Structure Instability and the Support of Low Strength or Buckling，and Summarizes some Prevention Measures on the Destruction of Underground Diaphragm Wall in the Light of these Failure Modes.
