加筋粉土的抗剪强度特性探讨

采用黄河堤防轻粉质壤土，通过三轴固结不排水剪切试验探讨了土工织物铺设层数及方式不同的加筋土体的抗剪强度特性。结果表明，当筋层较少时，加筋土体的部度不但不提高，反而可能下降，但有效强度指标增长显著；土工的的加筋作用随着轴向应变的增加而得到充分发挥，在实际工程中宜将土工织物铺设在大应变区。

Discussion about Optimization Design Methodology of Multiple Water-Table Well Systems

It is a less costly but more effiCient scheme to extract from multiple water-table wells systems groundwater which is then led to water-collecting basins and pressured to provide water for moderate cities andtowns in the middle and lower alluvial plain along the Yellow River. Being simple for operation and quick tocalculation. the design Process of such multiple wen systems. itetative hydraulic equilibrium calculation ofnetworks and turning regulation of electric diving pumps as proposed or adopted in this paper makes it possible fot the deSign of the System to approach an optimization.
