連續壁設計分析之實務考慮

Practical Considerations on Diaphragm Wall Analysis

摘要


連續壁之設計分析牽涉土壤力學理論、支撐及連續壁之結構行為。但分析之假設狀況常與現場實際情形有所出入,因而導致不合理之設計結果。本文針對連續壁之基本設計假設進行探討,包括分析模式、土壤強度、地盤反力係數、水壓力、超載壓力、支撐預壓等,現場施工控制對連續壁行為之影響亦有所提及。基本上連續壁之設計仍須倚賴經驗,純理論之分析結果易生錯誤。

並列摘要


Design and analysis of diaphragm wall requires knowledge on soil mechanics as well as behaviors of strut and wall. The design is generally based upon assumptions that deviate a lot from practice, which may lead to erroneous results. This paper discusses the nature of a few design assumptions, including analysis model, soil strength, modulus of subgrade reaction, water pressure, surcharge loading, preload of struts, etc. The effects of construction control on the behavior of diaphragm wall are also addressed. Basically, the design must rely heavily on experience, or else it may be completely incorrect.
