水泥土搅拌桩的桩身质量检测,通常采用取芯和留样进行无侧限抗压强度试验.水泥土无侧限抗压强度试验在很多规范中均有阐述,但对于试件试压时的含水率规定得并不够具体.含水率是影响水泥土抗压强度重要的因素之一,工程实践中,水泥土搅拌桩往往处于地下水位以下,其破坏时通常处于饱和状态,因此研究水饱和状态作为水泥土抗压试验的必要条件是很有意义的.

The test of pile body quality of cement soil mixing pile usually use the core and retention samples for unconfined compressive strength test. Unconfined compressive strength test of cement soil has been described in many codes,but not specific for the regulations of moisture content when testing pressure test. Moisture content is one of the most important factors affecting the compress strength of cement soil. In engineering practice,cement soil mixing piles were often under the ground water level which was usually destroyed in the saturated state. Therefore,it's very significant to study the water saturation state as a necessary condition for the compressive test of cement soil.
