|unconfined compressive strength;无侧限抗压强度；无侧限压缩
unconfined compression（无侧限压缩试验）是岩土工程中用于测定饱和粘性土抗剪强度的一种基本试验方法，尤其用于快速测定其不排水抗剪强度（Undrained Shear Strength, Su）。以下是详细解释：
定义与原理： 试验时，将圆柱形土样置于试验机上，仅对其轴向施加压力，而不施加任何围压（即无侧向约束，故称“无侧限”）。土样在轴向压力作用下发生压缩直至破坏。该试验基于饱和粘性土在快速加载（不排水条件）下，其破坏时的抗剪强度仅取决于土的内聚力（c），而内摩擦角（φ）近似为零的理论前提。
试验设备与过程：
结果与应用：

注：该试验仅适用于饱和粘性土（如粘土、粉质粘土）。对于砂土、砾石或非饱和土，此方法不适用。试验结果代表的是不排水条件下的强度，对于长期稳定性分析（排水条件），需要采用其他试验（如固结排水三轴试验）。该试验有时也缩写为UC Test (UCST)。
“Unconfined compression”是工程学和土力学中的专业术语，指材料在无侧向约束条件下承受轴向压力的状态或测试方法。以下是详细解释：
词义拆解
整体含义
该术语通常指无侧限压缩试验（Unconfined Compression Test），用于测定土壤、岩石等材料在无侧向约束时的抗压强度。
应用场景
与其他试验的区别
与三轴试验不同，无侧限试验无需施加侧向围压，操作更简单，但仅适用于黏性土等具有一定自支撑能力的材料。
公式示例
无侧限抗压强度（$q_u$）的计算公式为：
$$
q_u = frac{P}{A}
$$
其中，$P$为破坏时的轴向荷载，$A$为试样的横截面积。
