| Abstract:The row piles internal bracing system is commonly used in soft-soil area for foundation excavation retaining and protection. This paper analyzes the key factors in the design and construction, which affect the stability of this system. And based on a failure case of foundation pit engineering, the typical instability causes in row piles internal bracing are discussed with treatment countermeasures put forward. The excavation results show that the treatment is effective and safe. |
