第六十八條檢測(cè)壩的外坡坡比。每100 米壩長(zhǎng)不少于2處，應(yīng)選在最大壩高斷面或壩坡較陡斷面。水平距離和標(biāo)高的測(cè)量誤差不大于10 毫米；實(shí)測(cè)的壩外坡坡比不應(yīng)陡于設(shè)計(jì)坡比減1。
第六十九條檢查壩體位移。要求壩的位移量變化應(yīng)均衡，無(wú)突變現(xiàn)象，且應(yīng)逐年減小。當(dāng)位移量變化出現(xiàn)突變或有增大趨勢(shì)時(shí)，應(yīng)查明原因，妥善處理。
第七十條檢查壩體有無(wú)縱、橫向裂縫。壩體出現(xiàn)裂縫時(shí)，應(yīng)查明裂縫的長(zhǎng)度、寬度、深度、走向、形態(tài)和成因，判定危害程度。 上一頁(yè) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] [21] [22] [23] [24] [25] [26] [27] [28] [29] [30] [31] [32] [33] [34] [35] [36] [37] [38] [39] [40] [41] [42] [43] [44] [45] [46] [47] [48] [49] [50] [51] [52] [53] [54] [55] [56] [57] [58] [59] [60] [61] [62] [63] [64] [65] [66] [67] [68] [69] [70] [71] [72] [73] [74] [75] [76] [77] [78] [79] [80] [81] [82] [83] [84] [85] [86] [87] [88] [89] [90] [91] [92] [93] [94] [95] [96] [97] [98] [99] [100] [101] 下一頁(yè) |
