地矿测绘, 2020 本文以浙江天台大佛洞的含砾砂岩为例,进行了岩石天然状态与饱水状态下的单轴压缩对比试验,试验发现含砾砂岩在饱水状态下其单轴抗压强度明显下降,且弹性模量和泊松比等力学参数也出现一定的下降。因此,在实际工程中有必要考虑砂岩在吸水饱和后的强度变化情况。

Jianzhu Gangjiegou Jinzhan, 2021 中空夹层圆钢管混凝土短柱在轴压作用下,混凝土材料受到内外钢管约束处于三向受压状态,其抗压承载力较普通混凝土有较大提升。提升幅度与侧压应力有直接关系,侧压应力大小取决于截面尺寸及其所受轴力。现行设计方法认为同一构件在轴压和纯弯状态下侧压应力大小相同,对于偏压状态下的侧压应力如何考虑未明确说明。对此,引入与轴力相关的侧压应力系数β修正混凝土的本构关系,明确在各种受力状态下如何考虑侧压应力的影响。还提出一种应力积分算法用于计算短柱构件的极限承载力,得到短柱截面的轴力-弯矩(N-M)曲线。最后 ...
