黄土增湿方法的试验研究

EXPERIMENTAL STUDY ON LOESS HUMIDIFICATION

黄土增湿方法有预湿法和掩埋法。预湿法增湿时间较快,增湿程度易于控制,增湿效果较好,但无法批量增湿,需单个分别处理,工作量较大。掩埋法可以批量增湿,但增湿时间过长,增湿均匀性较差。土体含水量越高,增湿试验所需时间越短。

Loess humidification involves pre-wet and burial methods. The pre-wet method is good at short in time, easy centrol of humidification degree and final result, but poor at no way to achieve humidification in batch, handling individually and more work required. The burial method is good at humidification in batch, but taking time too long and poor in uniformity of humidification. The more loess is saturated with water, the shorter the time is required for humidification test.
