摘要江漢油區鹽間非砂巖儲層結構類型多,主要有孔隙型、孔隙裂縫型和裂縫型;粘土礦物含量較高;這種儲層主要是泥巖,含盆和白雲石,裂縫發育,並且巖性變化大。Secondly, the producing mechanism of crack in reinforced structure and factors which affect crack have been discussed, in the emphasis, the method is expounded, which applies first releasing then resisting, combination of releasing and resisting. in the method, flexible slit is applied firstly, which can make deformation of structure distributed, and decrease deformation energy, then the tiny expansion concrete and prestressed concrete with unbonded tendons are applied. and in the different phase, the compressive prestress is put on the concrete structure
其次,分析並論述了鋼筋混凝土結構裂縫產生的機理和影響因素,著重闡述了「利用先放后抗,抗放結合,綜合控制」的方法:即首先利用后澆帶,使混凝土結構分段變形,減小超長變形的影響;並採用微膨脹混凝土技術及無粘結預應力混凝土技術,分階段對混凝土結構施加一定的預壓應力,從而減小或完全抵消混凝土結構因混凝土硬化收縮引起的拉應力;再結合一些其他措施,成功實現鋼筋混凝土結構的超長無縫設計與施工。
