残积红粘土的力学特性试验研究

Experimental Study on Mechanical Strength of Residual Laterite

通过对某建筑工地地基土的单轴固结压缩和固结不排水三轴剪切试验研究，得出了其地基土—残积红粘土的固结压缩特性，以及原状土和重塑土在不同围压下的破坏形式的变化，主应力差（α1-α3）和有效应力比（α1′／α3′）与轴向应变ε之间的关系，原状土和重塑土的孔隙水压力和轴向应变ε的关系等一系列的力学特性。

After experimental study on subsoil of residual laterite with consolidated uniaxial compression test and consolidated undrained triaxial compression test, a series of conclusion can be drawn such as its consolidated compression characteristic, the failure style change under different surrounding compression about undisturbed and remoulded clay, the relation between deviator stress （ α1/α3 ）, effective stress ratio（α1′/α3′ ） and axial strain ε, the relation between interspace water compression and axial strain ε about undisturbed and remoulded clay.
