matrix suction meaning in Chinese

基质吸力

Due to the contribution of matrix suction to the shear strength of rock mass and the harmful function of temporary additional water load are considered , the checking computation result of the above mentioned method conforms to reality better than those of the previous methods
该程序考虑了非饱和带基质吸力对岩体抗剪强度的贡献以及暂态附加水荷载的不利作用（若具备含水量与岩体强度指标之间的关系，还能考虑水对岩体的软化作用），使计算结果更贴近实际。
Based on the knowledge of characteristic of unsaturated soils . the law of suction change with moisture content and density is got from suction experiment , which revealed that the matrix suction changes obviously with density especially in low moisture content , and with the same moisture content , if the density is gradually added , the value of matrix suction first is lowed , then added and finally lowed , this phenomenon is probed into in this paper
基于对非饱和土特性的认识，进行了基质吸力的试验研究，得到了基质吸力随含水量和密度的变化规律，试验揭示出：基质吸力随密度的变化是明显的，含水量越低，这一趋势越明显，在含水量相同的情况下，当砂土从疏松状态逐级变密时，吸力值经历变小、变大、又变小的过程，文中对造成这一现象的原因作了初步分析。
