[0002] Soft soil foundation is a kind of bad foundation in engineering. Improper treatment can easily cause uneven settlement of building foundation or roadbed, thus leading to damage or even collapse of buildings or roads. Therefore, measures need to be taken in engineering to improve the stability and bearing capacity of the foundation. Common soft foundation treatment methods are generally divided into the following two types: Shallow treatment methods: reinforced soil, replacement method, on-site medium and shallow solidification treatment method, compaction, etc. Deep treatment methods: deep mixing method, drainage consolidation method, lime pile method, high-pressure jet grouting method, etc. Therefore, it is divided into on-site (in-situ) solidification and ex-situ solidification according to the solidification form.
