vertical multiple meaning in English

纵复接

Analysis based on a large amount of data about the load - settlement , pile soil stress ratio and stress distribution obtained from the model tests shows that in the horizontal - vertical multiple reinforcing system , the horizontal reinforcing function of the geocell reinforced gravel mattress , the vertical reinforcing function of the gravel pile , the system of load transfer and supporting formed through interaction and working together mechanism between gravel pile composite foundation and geocell reinforced gravel mattress are the main mechanism of its load capacity improvement , settlement and asymmetrical settlement reduction
试验结果分析表明：在土工格室碎石垫层碎石桩复合地基这一水平向竖向多元复合地基共同作用的加固体系中，结合了土工格室碎石垫层的水平向增强体作用和碎石桩的竖向增强体作用；土工格室碎石垫层和碎石桩复合地基相互作用，共同工作构成的荷载传递和支撑体系是其提高承载力，减少沉降和差异沉降的主要机理。
