为探究城市建筑拆除固废再生骨料部分或全部取代天然骨料用于粗粒土路基填料的可行性,开展不同再生骨料取代率、含水率、围压和剪应力比等组合下的室内大型静动三轴试验,定量研究土性参数和应力状态对试样抗剪强度和累积塑性应变特性的影响规律。基于半对数坐标下累积塑性应变发展的多阶段特征,分别考虑不同阶段塑性变形累积速率以及相邻两阶段的塑性变形累积速率的差异,提出适用于建筑固废再生骨料路基填料的新型安定行为判定准则。研究结果表明:再生骨料路基填料试样的累积塑性应变随含水率和剪应力比的增大而增大,当再生骨料路基填料试样在剪应力比为0.3和0.5时,抗累积变形性能与天然骨料路基填料试验所得的抗累积变形性能接近,综合考虑抗剪强度和累积塑性变形特性的再生骨料路基填料最优取代率为85%;新安定行为判定准则具有较高的准确性,可为相似路基填料的长期路用性能评定提供理论依据。

PIT tests are usually performed when a mass distribution of High Explosive(H.E) projectile fragments is required. This paper shows the underwater detonation effects of 60 mm, M90 H.E. mortar bomb filled with Comp. B on cylindrical concrete structure(concrete pipe closed at one end-similar to a PIT test)which is 2 m high(inner height) with inner diameter of also 2 m. Thickness of both wall and bottom of a pipe is 0.35 m. Detailed characteristics of concrete which is used for manufacturing of a pipe are specified. Mortar bomb is submerged directly in to the water(no free airspace around the bomb) with the nose pointing to the bottom of a pipe. Number and mass of fragments after detonation are presented by table and photographs. Fragments of dummy fuze, through which blasting cap was protruded, are collected and reassembled to form a shape of a fuze after detonation where expanding of fuze material due to a detonation products is visualized. After underwater detonation, detonation of the same mortar bomb is performed in an empty pipe and the effects of this kind of detonation are observed. Distance at which fragments generated from submerged mortar bomb will not reach concrete pipes wall is also determined.
