Evolution law of mechanical properties of red mudstone fill material under long-term relative humidity cycles [PDF]
Red mudstone fill material (RMF) is highly sensitive to water content. Evolution on mechanical properties of RMF subgrade during long-term relative humidity cycles would be induced by the change of seasons.

Shuitu Baochi Xuebao, 2023 为探讨植被根系对干旱内陆河流岸坡冲刷过程的定量影响,以塔里木河为研究对象,采用BSTEM模型模拟分析的方法,模拟了8个典型岸坡在2016—2017连续2个水文年的冲刷过程,重点分析骆驼刺、红柳、芦苇、甘草、胡杨、白刺等6种典型荒漠植被根系对河岸冲刷过程的定量影响。结果表明:(1)塔里木河河岸崩塌基本发生于落水期和枯水期,岸坡稳定性在水文年内呈周期性变化,枯水期和涨水期安全系数Fs略有波动,整体上呈稳定状态,河岸稳定,在洪水期高水位处Fs短暂升高,随后随着水流的冲刷淘蚀以及水位下降,Fs不断下降 ...
