- 摘要:
- 天津经济技术开发区和保税区的发展，需要对大量的低洼地进行回填，为了利用天津碱厂排出的大量工业废料取代价格较高的普通回填用土，自1992年以来对碱渣的性质做了大量研究工作，相继提出以不同材料，按不同配比拌和碱渣形成碱渣土进行低洼地填垫的方案，并对其物理力学指标通过室内和现场试验进行了检测，结果表明碱渣土可以用于低洼地的回填。
With the development of Tian Jin Economic Technological Area and Tax Free Zone, a lot of low land need to be filled up for lwaste development. In order to use large amount of industrial waste materials discharged from The Tian Jin Alkaii Factory for the land filling in stead of using the ordinary soil with higher price, a lot of study works on performance of alkai residue have been done since 1992. Andthen a proposal of low a land filling based on mixturing alkali residue with different materials and different ratiQ to form the alkali residue soil was provided. Lab and field tests of physical and mechahical properties were carried out as well. The inspection results show the alkali residue soil can be used for low land fil1ing.1997,4(4): 1-8 收稿日期：1997-3-24参考文献：
