摘要]榆林城墙面临消亡的危险,对其加固已迫在眉睫,故提出采用改性土进行加固保护施工方案。为研究加固后城墙的耐久性,在榆林素土中加入少量的掺合料(料姜石、水泥、熟石灰)来改善土体的耐盐性,并对榆林素土和料姜石的化学成分和易溶盐进行分析。试验和实践表明,利用配比为5%水泥、5%熟石灰、10%料姜石、80%黄土的改性土体来夯筑加固城墙,加固后的城墙具有良好的耐久性,这种加固方案能够保持城墙的原貌。

Abstract: Yulin City Wall faces the danger of disappearing and the reinforcement is immediately needed. The reinforcement protection and construction method of improved soil reinforcement was put forward. In order to research the durability of the reinforced city wall, little amount of mixed stuff, including Liaojiang stone, cement, and hydrated lime, were added into the Yulin soil to improve its salt tolerance property. Chemistry analysis and salt dissolve analysis were proceed on the Yulin soil and Liaojiang stone. The experiment and practice demonstrate that rammed wall with 5% cement, 5% hydrated lime, 10% Liaojiang stone and 80%soil has a well durability, which can maintain the original site of original features.

Keywords: improved soil; city wall; Liaojiang stone; reinforcement; mixed stuff; anti-salt dissolve property
