The main contents are as follows. By the experiments of two joints under low-reversed cyclic loading, the paper analyzes the failure pattern, energy dissipation, ductility and cracking in the joint cores, evaluates the seismic performances and anti-crack behaviors of the joints, and deduces the anti-crack formula of the subassemblage and prestressed frame joint. Through the finite element analysis software Ansys , the paper analyzes the specimens nonlinearly, and the theoretical analysis results are well consistent with those of the experiment.

主要内容包括：通过两榀节点在低周反复荷载作用下的试验，分析其破坏形态、耗能能力、延性性能和节点核芯区裂缝开展情况，评估节点的抗震性能和抗裂能力，推导出预压装配式框架节点的抗裂验算公式；并运用Ansys对试验中的节点进行了非线性分析，计算结果与试验结果基本吻合。

As one kind of tignum, concrete is widely used in infrastructure construction in our country. The research of the concrete crack resistance is urgent need, which was due to the common existing of concrete structure crack.

混凝土作为一种建筑材料广泛地应用于我国基础设施建设中，然而混凝土建筑物出现裂缝的现象十分普遍，因此，对混凝土抗裂性能的研究显得尤为紧迫和突出。

Tectonic condition is the key factor for igneous rock reservoir, which produce crack and improve reservoir character, abundant generating rock is the foundation for igneous rock reservoir, lithology condition is the important supplement for igneous rock reservoir, it is easy for trachyte to produce crack.

综合分析构造条件是火山岩成藏的关键，其产生的裂缝改善了火山岩储层的储集性能；充足的油源条件是火山岩成藏的基础；岩性条件是火山岩成藏的重要补充，即粗面岩容易在构造作用下形成构造裂缝，最终形成火山岩油气藏。

When a horizontal well is transversally fractured with multiple stages, initial crack can induce the secondary change of the wellbore stress, producing the induced stress ield which has an inluence on subsequent crack initiation.

水平井分段压裂时，形成的初始裂缝会诱发井筒周围应力分布二次改变，产生诱导应力场。诱导应力场将会对后续裂缝起裂产生影响。
