1) soil settlement
土壤沉降
2) degradation in soil
土壤降解
1.
The weight losses and changes in molecular weight and surface morphology were investigated after degradation in soil and in an aqueous of porcine pancreas lipase for different times.
结果表明,土壤降解和酶降解都经过表面腐蚀过程,无定形态首先降解,样品质量逐渐损失,分子量逐渐减少;结晶度对膜的腐蚀形貌有很大的影响,降解速率都随4HB含量的增加而增加;脂肪酶降解速率比土壤降解速率快,但分子量减少的程度不及土壤降解,并且在降解过程中出现了小分子量的低聚物。
4) sedimentation of foundation soil
基土沉降
1.
From the aspect of controlling the sedimentation of foundation soil for buildings,it adopts soil displacement,foundation style selection and so on to solve weak foundation soil problems of buildings,through selection,design,measurement and cost-estimation of the foundation of the main controlling building in Baijia 220 kV substation of Dushan village,Zhangzhu .
分析了江苏苏南地区长江冲积平原地形、地质条件特点,从控制建筑物地基土沉降角度出发,通过对无锡宜兴市张渚镇渎山村220kV百家变电所主控楼基础的选型、设计、实测、工期、造价、比较等,采用换土和选择合理的基础型式等手段,解决软弱地基土的建筑物基础问题。
5) solum settlement
土层沉降
6) Settlement of soft clay
软土沉降
