软土从广义上说,就是强度低、压缩性高的软弱土层。可将软土划分为软粘性土、淤泥质土、淤泥、泥炭质土及泥炭五种类型。软土地基加固的方法很多,比如可采用塑料排水板。塑料排水板是带有孔道的板状物体,插入土中形成竖向排水通道。因其施工简单、快捷,目前国内广泛应用,效果亦佳。其余还有换填土、砂井、生石灰桩、粉喷桩、旋喷桩、挤实砂桩等加固施工方法。 Soft soil in a broad sense, is the low strength, high compressibility of the soft soil. Soft soil can be divided into soft clay, muddy soil, silt, peat soil and peat five types. There are many ways to reinforce soft ground, such as plastic drainage board. Plastic drainage board is a plate with a hole in the object, inserted into the soil to form a vertical drainage channel. Because of its construction is simple, fast, widely used at home, the effect is also good. The rest there are for filling, sand wells, lime pile, DJM, jet grouting piles, sand piles and other reinforcement consolidation methods.
