Analysis of 2 D seismic data over 4 500 km in length from the Madura Strait Basin in the East Java Sea reveals seismic re?ection characteristics of reefs and associated sedimentary bodies, including asymmetrical or symmetrical dome re?ections, slope progradational re?ections, chaotic re?ections and discontinuous strong re?ections inside the reef, which onlap the ?ank of the reef. It is concluded that the developmental paleo-environment of most reefs is mainly conducive to shallow marine carbonate platform facies and platform margin facies, based on well core data, variations in seismic facies and strata *** formation and evolution of all reefs are primarily in?uenced by the tectonic framework of the Madura Strait Basin. Platform margin reefs are principally controlled by two types of structures: one is a series of E-W trending Paleogene normal faults, and the other is an E-W trending Neogene inversion structures. In addition, wave actions, tidal currents and other ocean currents play an accelerated role in sorting, rounding and redeposition for the accumulation and evolution of reefs. Tertiary reefs in the MSB can be divided into four types: 1) an open platform coral reef of Late Oligocene to Early Miocene, 2) a platform margin coral reef controlled by normal faults in Late Oligocene to Early Miocene, 3) a platform margin Globigerina moundreef controlled by a "hidden" inversion structure in Early Pliocene, and 4) a platform margin Globigerina mound-reef controlled by thrust faults in the early Pliocene. Patterns of the formation and evolution of reefs are also suggested.

为研究钢纤维(SF)与聚丙烯纤维(PPF)混杂后对再生混凝土(RAC)抗冲击性能的影响,采用落锤弯曲冲击试验装置对素RAC、SF/RAC、PPF/RAC和SF-PPF/RAC进行抗冲击试验;分析了不同纤维掺量和掺入方式对RAC抗冲击性能的影响;采用数理统计模型对冲击试验结果进行拟合和失效概率预测,并对SF-PPF/RAC抗冲击性能的阻裂增强机制进行深入分析。结果表明:单掺或混杂纤维均可提高RAC的抗冲击性能;其中混合掺入体积分数为1.5vol%的SF和体积分数为0.9vol%的PPF时,RAC抗冲击耗能的提高幅度最大,RAC基体的延性和韧性最佳。SF-PPF/RAC的抗冲击次数很好地服从两参数Weibull分布。SF与PPF混杂对改善RAC的抗冲击性能呈现出优异的混杂增强效应。
