Secondly , true taixial test by load in three different principal stress direction for study on soil anisotropic deformation characteristic are processed . lateral deformation relative to load direction , lateral deformation relative to lateral direction and the stess - strain relationship in load direction are analyzed , and soil anisotropic deformation characteristic on the three aspects of elastic ratio , poisson " s ratio and the property of compliment matrix are completely analyzed too 其次,為揭示土體各向異性變形特性,有針對性進行了三主應力分別單向加荷的真三軸試驗研究,分析相對于加荷向的側向變形、互為側向的側向變形、不同主應力加荷向的應力應變關系各向異性性狀。
Three different aspects of anisotropic deformation including lateral strain , relative proportional relation of lateral strain and strain in load direction , and train increment induced by unit stress increment in load direction will be delicately analyzed . the stress strain relationship in different principal stress load direction can be reflected in the anisotropy of tangent elastic ratio or strain increment in load direction induced by unit stress increment in load direction 側向變形可以從側向應變、側向應變與加荷向應變之間的相對比例關系或側膨脹系數以及加荷向單位應力增量所引起的側向應變增量三個不同方面深入細致地分析研究;不同主應力加荷向的應力應變關系各向異性可以反映在切線彈模以及加荷向單位應力增量引起的加荷向應變增量的差異中。
As a new building material for reinforcement and strengthening , the supply and application of epoxy resin structural adhesive are more and more , but standard structural adhesive itself has the disadvantages such as worse working performance , low bond strength , brittleness , low elastic ratio . so it is necessary to modify the structural adhesive 環氧樹脂建筑結構膠作為一種加固修復的新型建筑材料的需求量變得越來越大,應用的范圍也越來越廣,但目前環氧樹脂結構膠存在工作性能不好、粘接強度不高、脆性大、彈性模量較低等缺點,所以有必要對其進行改性研究。
Sem results showed that , microcrack induction ability of these materials was markness . in a word , the working performance , bond strength , elastic ratio , brittleness of structural adhesive modified by proper materials were improved , satisfied engineering requirement . its modifying technology was simple and convenience , has very high active extending sense and application value in structural adhesive modifying field 采用適當的納米材料改性環氧樹脂結構膠的綜合性能優良,能滿足工程應用的要求,而且改性工藝簡單可行,在結構膠改性領域里有積極的推廣和應用價值。
