Although there are many experiments under multiaxial stress states, most of the results mainly concern to the strength and failure criterion of concrete.
虽然三轴试验较多，但是主要是针对三轴情况下混凝土的强度(破坏准则)，没有具体针对不同围压应力比下的应力—应变关系做出研究。
With a simple form, the criterion can reflect the concrete strength precisely not only under uniaxial stresses but also under multiaxial stresses.
该准则的特点是：形式简单，不仅能正确反映混凝土单轴应力状态下的强度，而且能很好地反映多轴应力状态下混凝土的强度。
