At present, the commonly used methods for testing of the vertical compressive capacity of single piles at home and abroad are the static compressive loading tests and the high-strain dynamic loading tests on single piles.
目前国内检测单桩竖向抗压承载力常用的方法有静载荷试验法和高应变动力测试法。
Based on the constitutive law of confined concrete, the axial compression ultimate analysis of the circular concrete column with spiral hoop is investigated, and the calculated methods of the ultimate compressive capacity and the ultimate deformation are presented.
本文利用侧限混凝土的本构关系，对采用螺旋箍筋的混凝土圆柱在单调轴压荷载作用下进行极限状态分析，并提出了极限承载力和极限变形的`计算方法。
The vertical mortar joint cracked and the mortar in horizontal mortar joint dropped when the specimens were destroyed. A formula is provided to calculate the compressive capacity of concrete block masonry when the mortar strength is very low.
试件破坏时大多出现竖向灰缝开裂、水平灰缝砂浆向外鼓落的情况。提出了适用于砂浆强度很低的灌孔砌块砌体的抗压强度计算公式。
