临淄地区包气带及地下水中酚、氰化物的污染迁移机理

依据环境水文地质条件、污染源的状况和酚、氰化物对地下水长期污染状况，综合临淄地区现场资料对酚、氰化物的污染特性及迁移机理作初步研究。研究表明，淄河沿岸区和冲沟内砂砾石分布区是酚、氰化物进入地下水的主要通道，大气降水是促进酚、氰化物解吸迁移的主要因素。虽然目前研究区域内已无含酚、氰化物的污水直接排放，但吸附于较厚细颗粒包气带土层中的酚、氰化物还将在较长时间内存在并缓慢进入地下水中，其含量将会随时间的推移而呈减少趋势。

Finite Element Method for Elastic Resistance in the Design of Supporters in Deep Foundation Pits

The design of multi supporting plate pile for deep foundation pits is discussed in this paper using the finite element method for elastic resistance. Compared with the traditional static limit equilibrium method, it can give the top displacement of the pile and the bending moment of the pile during different digging steps and simulate the course of digging. It can coordinate the deformation of the supporting structure and the soil and determine the minimum of the bending moment of the pile and the anchoring forces of the anchors. This method has been used to design the supporting structure of a deep foundation pit in Qingdao with satisfactory results.
