本数据集整理和收集了项目实施期间（2018-06），井筒环空带压实验数据集，测量要素含有环空、压强、径向应变、环向应变等字段数据。该项目室内实验数据收集时间始于2018年6月1日，止于2018年6月31日，共计开展室内实验276组次，实验数据集完全开放共享。通过对不同环空腔进行模拟加压，由于管柱腔体处于封闭状态，使得环空腔在压力作用下会影响管柱内腔的体积变化，体积的变化将会进一步影响管柱受到应力作用，产生应变。因此，该实验设计主要是在不同加压条件下分别探究不同环空层管柱的应变规律。

The collection of indoor experimental data for this project began on June 1, 2018 and ended on June 31, 2018. A total of 276 sets of indoor experiments were conducted, and the experimental dataset was fully open for sharing. By simulating pressurization of different annular cavities, due to the closed state of the column cavity, the annular cavity will affect the volume change of the column cavity under pressure, and the volume change will further affect the stress and strain of the column. Therefore, the experimental design mainly aims to explore the strain patterns of different annular layer columns under different pressure conditions.
