洱海区域流砂地质条件下沉井设计计算研究

Study on design calculation of caisson under the geological condition of sand flow in Erhai

以大理市洱海环湖截污工程二标段施工为实例,结合现场施工技术组织,深化设计现有沉井施工的设计计算原理。经工程实践验证,满足类似洱海区域流砂地质条件或其他不良地质条件下的沉井设计施工。

Taking the construction of the two bid section of the Erhai Lake Sewage Interception Project in Dali as an example,this paper combines with the on-site construction technology organization,and designs the principle of existing caisson construction. It is verified by engineering practice that its design of open caisson under similar geological conditions in Erhai area or other unfavorable geological conditions are satisfied.
