竹筋加筋土技术就是在土中掺入或铺设适当的竹筋，以代替土工合成材料和钢材等传统的加筋材料，从而改善土体的强度与变形特征。基于川南地区常见的粉质黏土软弱路基的特点，结合当地丰富的竹材资源，经过现场试验研究，总结了竹筋处理粉质黏土填筑乡村公路路基所采用的施工工艺及关键技术，包括竹筋防腐处理、竹筋铺设方式、粉质黏土改良处理等。结果表明所采用的竹筋加筋土技术施工简单、易操作、成本低且环保。
竹觔加觔土技術就是在土中摻入或鋪設適噹的竹觔，以代替土工閤成材料和鋼材等傳統的加觔材料，從而改善土體的彊度與變形特徵。基于川南地區常見的粉質黏土軟弱路基的特點，結閤噹地豐富的竹材資源，經過現場試驗研究，總結瞭竹觔處理粉質黏土填築鄉村公路路基所採用的施工工藝及關鍵技術，包括竹觔防腐處理、竹觔鋪設方式、粉質黏土改良處理等。結果錶明所採用的竹觔加觔土技術施工簡單、易操作、成本低且環保。

Bamboo reinforced earth technology, which uses bamboo bar instead of the traditional geosynthetic materials and steel reinforcement material, is used to improve the strength and deformation characteristics of soil in different degrees with appropriate bamboo bar in the soil. Based on the characteristics of silty clay weak subgrade of south Sichuan, construction methods and key technologies are introduced by field tests under the background of local abundant bamboo resources, including bamboo ribs embalmed, bamboo ribs laying way, silty clay treatment and so on. The result shows that construction technologies are easy to operate with low?cost and environmental protection effect.
