Relationship between rectification moment and angle of shield based on numerical simulation

The finite element method is used to simulate the rectification process of shield machine, to study the relationship between rectification moment and angle and to explore the influence laws of different soil parameters and buried depth on rectification moment. It is hoped that the reference value of rectification moment can be offered to operator, and theoretical foundation can be laid for future automatic rectification technology. The results show that the rectification moment and angle generally exhibit good linear behavior in clay layers with different soil parameters or buried depths, and then the concept of rectification coefficient, that is, the ratio of rectification angle to rectification moment, is proposed; different soil parameters and buried depths have different influences on rectification coefficient, in which elastic modulus has great influence but others have little influences; the simulations of rectification process are preformed in clay layers with different elastic modulus, and fitting results show that elastic modulus and rectification coefficient present the quadratic function relation.

荥阳西司马商周墓地再研究

西司马墓地是郑州近来年发现的最为重要的一处商、周墓地,墓地规模大,墓葬排列有序,出土物丰富。通过研究,知其是一处殷人连续使用的墓地,这对郑州地区商、周之际墓葬的研究有重要作用,对殷人如何向周人转变也具重要意义。
