The research results indicate that as the prestress increases , thepeak value of stress waves in the anchored surrounding rock gradually increases, and the attenuation rategradually decreases. Inereasing the prestress of the anchor rod significantly reduces the peak value of ten-sile waves at the free end of the anchor; As the prestress of the anchor specimen increases , the axial forceloss of the anchor increases faster, and the axial force loss rate shows a quadratic linear increase; whenthe prestress is small, there are more cracks in the surrounding rock at the anchoring free end. Undermultiple impacts, the crack distance is relatively close, and as the prestress increases, the degree ofdamage at the free end weakens; as the prestress increases, the maximum displacement during pullingdecreases. The original specimen that was not subjected to dynamic load does not show significant damageafter pulling. After dynamic load, as the preload increases , a certain degree of spliting failure occurs atthe anchor end , and the degree of splitting failure becomes weaker as the prestress continues to increase.

The T, and its theory will explainthe instability of lac resin and direct the storage temperature when it is confirmed. Under the polymerglass transition theory, we used X-ray Difraction(XRD), Dierential Scanning Calorimetry ( DSC )and Dynamic Themomechanical Analysis (DMA) to verify lac-resin's 7. According to the XRD graphand its degree of crystallinity of 2. 93% , we confirmed that lac resin is amorphous polymer. The averagespecific heat capacity difference of the five DSC measurements was 0.071 J/(g ·K). The DMA meas.urement showed the inflection point of storage modulus was 36.0 C, the peak value of loss modulus and loss factor were 27.3 ℃ and 36.0℃ respectively. Combining the XRD, DSC and DMA results, wecould confirm that lac resin possess the glass transiton and T,. The T, was 27. 3 ℃ under the DSC measurement and was 36.0 9C under the DMA measurement. The interpretation of the instability of lac resinwith the glass transiton and 7, was: when the storage temperature is below 7,, lac resin could be storedfor a long time even if the physical aging may affect the lac-resin's property; when the storage temperatureis above 7' , the storage time will be shortened because the reactive end-grups could motion which couldcause a chemical reaction. Therefore the storage temperature of lac resin should be below its 7. Related Articles | Metrics
