新近吹填超软土地基浅层加固技术卸载标准探讨

Unloading criterion on improvement technique of shallow ultra-soft soil foundation formed by hydraulic reclamation

新近吹填超软土地基浅层加固对沉降控制要求不严格,因此,现有的卸载标准不完全适用于该类地基。鉴于此,通过理论方法建立了该类地基浅表层加固卸载标准的判别条件,并结合工程应用证实该判别条件是现有卸载标准的有效补充方法之一。

For the treatment technique of shallow ultra-soft soil foundation formed by hydraulic reclamation, the ground settlement is not strictly controlled, so the existing unloading criterion does not apply to such foundations. In view of this, the unloading criterion is established by theoretical methods for the treatment technique of shallow ultra-soft soil foundation formed by hydraulic reclamation. Then it is demonstrated in engineering practice that the theoretical criterion is one of the effective complement methods for the existing unloading criterion.
