摘要

本文以實例說明一般認為不擾動地盤土壤與不影響鄰近建築物之SMW工法，其在N≦4與ω≧LL之軟弱粘土沈泥（ML-CL）地盤與N≦10之鬆砂地盤，仍如預壘排樁鑽掘破壞地盤一般造成鄰房損壞，而且在軟弱粘土沈泥地盤SMW壁體仍會包泥，造成壁體滲水。SMW工法之鄰房保護方法與預壘排樁相同。

This paper narrated cause of building damaged induced by the SMW method, which is regarded as a construction method that will not cause soil disturbance and damaged to adjacent buildings. In reality, SMW method disturbs the earth like Bored-pile method when it is constructed, particularly in soft clay with N≦4 orω≧LL, and in loose sand with N≦10. In these soils, the SMW walls may contain mud and leak. To protect adjacent buildings, the SMW method most adopt the same precautious measures as the Bored-pile method.
