By using the data of the experiment , this dissertation has analysed the relationship between the dynamic parameter and the self - property , then based on the elastic half space theory of the dynamic foundation , this dissertation get the method to measure the density of silt or sand subsoil using instantaneous implusion 本文通過試驗獲得的數(shù)據(jù),分析地基土的動力參數(shù)與土體的本身性質(zhì)之間的關(guān)系,并應(yīng)用動力基礎(chǔ)半空間理論,得到了全新的利用瞬態(tài)錘擊法來測定粉砂土的密實度的方法。
Base on the elastic half space theory of the dynamic foundation , analyzing the relationship between the vibration frequency and the dynamic shear modulus of the soil , a relationship between the vibration frequency and the self - property of the subsoil can be carried out . that is the expression about the relationship between the vibration frequency and the density of the soil can be carried out 通過采用動力基礎(chǔ)半空間理論,分析錘擊產(chǎn)生的地基土的振動頻率與地基土的動剪切模量之間的相關(guān)關(guān)系,就又可以得到地基土自振動頻率與土體本身性質(zhì)之間的關(guān)系,即與土體的密實度之間的關(guān)系。
