摘要
通过对海安双线船闸闸首施工过程中结构受力敏感部位和关键点的控制指标进行监测,保证施工的安全性,检查施工过程的合理性。监测结果表明:双线施工及底板分块施工对该块影响较大,对其他施工块的影响很小,底板下地基应力、底板沉降和结构应力随时间总体变化趋势相似。施工过程中,结构应力维持在较小范围内,满足规范和施工要求。
To assure the safety and reasonability of double-line ship lock project construction process in Hai＇an,we monitor several control indices of sensitive parts and key location of the lock head. The results show that the blocked construction has a greater impact on the constructing block and less on others. Control indices including the structure settlement,soil pressure and structure stress have similar variation tendency. The structure stress fluctuates within a small scope,which satisfies the requirement of the construction code.
