潍坊滨海盐渍土地区城市道路设计研究

Study on Design of Urban Road in Coast Saline Soil Area of Weifang

潍坊滨海开发区地处环渤海地区滨海盐渍土分布区，土质为氯盐渍土，含盐量2．10％～2．40％，为中度盐渍土。由于盐渍土具有三相转换、溶陷、盐胀、腐蚀的工程特性，导致道路病害屡屡发生，处理不当易造成巨大经济损失。依托潍坊滨海地区盐渍土地区的具体工程，提出采用石渣结合强夯处理路基的综合措施，排水模式选用适合滨海水城建设，且符合海绵城市建设的缓冲式排水模式；管材选择抗腐蚀或做防腐处理的管材，并取得良好效果。

Weifang Coast Development Area is located at the coast saline soil distribution area in the central area of Bohai Sea. Its soil property is chlorine saline soil, and its salt content 2.10%~2.40% is the moderate saline soil. The saline soil will lead to the road fault repeatedly happening because of its 3-phase conversion,melt sinking, salt heaving, corrosion and other engineering characters. The improper treatment is easy to cause the huge economic loss. Relying on the practical projects in the saline soil area of the coast area in Weifang, the article puts forward the comprehensive measures of stone slag combined with dynamic compaction to treat the roadbed. The selection of drainage mode is suitable for the construction of coast water city, which conforms to the buffered drainage mode in the construction of sponge city. The anti-corrosive or antiseptically treated pipe materials are selected with the good effect.
