In order to study the effect of organic matter composition on the dynamic strength characteristics of peat soil in Dianchi Lake, an indoor dynamic triaxial test was carried out on saturated remolded peat soil with different organic matter content. The effects of different organic matter content, consolidation pressure and vibration frequency on the dynamic strength curve of remolded peat soil were studied. The dynamic strength indexes of remolded peat soil under different organic matter content, vibration frequency and cyclic vibration times were analyzed. The conclusions are as follows: When other conditions are the same, the dynamic shear stress of remolded peat soil increases with the increase of consolidation pressure, vibration frequency and organic matter content. The content of organic matter has the greatest influence on the dynamic strength of remolded saturated peat soil, and the dynamic strength index of soil has an obvious positive correlation with the increase of organic matter content. The dynamic strength of remolded saturated peat soil is less affected by load vibration frequency, and the dynamic strength index increases slightly with the increase of vibration frequency. The cyclic vibration times have a negative correlation with the dynamic strength of remolded saturated peat soil.
