三峡工程升船机基础施工期监测初步分析

Analysis on monitoring of TGP's ship-lift during foundation construction

本文简要分析了升船机上闸首基础岩体随上部建筑物施工过程的沉降变形、水平变形情况和基础斜坡段接缝开度的基本资料情况。初步分析认为,基础岩体变形合理,基础斜坡段接缝开度变化趋于稳定,年变化量小于0.3mm,符合大体积混凝土温度变形的正常规律,满足设计要求,目前建筑物安全状态正常。

This paper briefly analyses settlement and horizontal deformation of the foundation rock at chamber head of the ship-lift during upper structure construction, also analyses the basic data about the open joint of the slit in the foundation slope section. The preliminary analysis indicates that the deformation of the foundation rock is reasonable, the open joint of the slit in the foundation slope section tends to be stable,the variation in one year is below 0.3 mm, it adheres to the normal roles of temperature deformation in mass concrete, and it adheres to the design requirements, the building's safety condition is normal at present.
