|unconfined compressive strength;無側限抗壓強度；無側限壓縮
unconfined compression（無側限壓縮試驗）是岩土工程中用于測定飽和粘性土抗剪強度的一種基本試驗方法，尤其用于快速測定其不排水抗剪強度（Undrained Shear Strength, Su）。以下是詳細解釋：
定義與原理： 試驗時，将圓柱形土樣置于試驗機上，僅對其軸向施加壓力，而不施加任何圍壓（即無側向約束，故稱“無側限”）。土樣在軸向壓力作用下發生壓縮直至破壞。該試驗基于飽和粘性土在快速加載（不排水條件）下，其破壞時的抗剪強度僅取決于土的内聚力（c），而内摩擦角（φ）近似為零的理論前提。
試驗設備與過程：
結果與應用：

注：該試驗僅適用于飽和粘性土（如粘土、粉質粘土）。對于砂土、礫石或非飽和土，此方法不適用。試驗結果代表的是不排水條件下的強度，對于長期穩定性分析（排水條件），需要采用其他試驗（如固結排水三軸試驗）。該試驗有時也縮寫為UC Test (UCST)。
“Unconfined compression”是工程學和土力學中的專業術語，指材料在無側向約束條件下承受軸向壓力的狀态或測試方法。以下是詳細解釋：
詞義拆解
整體含義
該術語通常指無側限壓縮試驗（Unconfined Compression Test），用于測定土壤、岩石等材料在無側向約束時的抗壓強度。
應用場景
與其他試驗的區别
與三軸試驗不同，無側限試驗無需施加側向圍壓，操作更簡單，但僅適用于黏性土等具有一定自支撐能力的材料。
公式示例
無側限抗壓強度（$q_u$）的計算公式為：
$$
q_u = frac{P}{A}
$$
其中，$P$為破壞時的軸向荷載，$A$為試樣的橫截面積。
