31、输变电工程通用设计35kV配电线路金具分册（2013年版）江西省电力公司农网输变电工程通用设计35kV线路分册（2009年版）1.2 工程建设必要性1）满足万合镇负荷需求，缓解樟塘变的供电压力万合镇目前没有电源点布点，目前其负荷全主要由樟塘35kV变电站供带，随着万合镇的用电负荷的不断上升，根据上述负荷预测；到2016年万合镇的最大负荷将达到4.79MW；樟塘变目前的主变容量只有4.5MVA；樟塘变将会过负荷，为了满足D类地区的负荷需求，缓解樟塘变的供电压力，因此新建万合变是很有必要的。2）完善泰和县D区35kV电网结构，提高该地区供电可靠性樟塘变承担万合镇的10kV供电半径最长的超过15km
32、，供电半径过长，供电可靠性差，再者35KV网架全部为“葫芦串”式结构，网架十分薄弱。泰樟、化津、上马、沙龙、沙营、坎东、泰沿、上沙、沙樟线为单回路接线，且线径偏小，供电可靠性十分差，因此建设万合35kV输变电线路，优化D类网架结构，提高该区域供电可靠性是十分必要的。1.3 工程规模及设计范围1、工程规模:线路起于35kV樟塘变电站35kV构架，终点为新建35kV万合变电站35kV构架，线路亘长约11.2km，线路曲折系数为1.08。导线型号选用LGJ-150/25型钢芯铝绞线，地线选用OPGW-24B1-48光缆。2、设计范围:本工程为泰和县35kV万合输变电线路新建工程，位于泰和县万合镇、樟

34、施、开采的矿产及石场、油库及重要通信设施。6)尽量避让严重覆冰地区。7)尽量避免跨越民房。8)综合协调本线路路径与沿线已建线路及其它设施的矛盾。2.2 路径方案说明泰和县35kV万合输变电线路新建工程路径说明泰和县35kV万合输变电线路新建工程起自35k樟塘变构架，由于35kV樟塘变前边有房子、35kV樟沙线、樟泰线，线路出线需绕开35kV樟塘前面高压线路及房屋。如图（2-1）避开江背村庄，线路右拐至J3，然后线路走廊主要沿河渠，全线共6个拐角，至新建35kV万合变电站。全线避开房屋、村庄、万合镇。如图（2-2）泰和县35kV万合输变电线路新建工程路径方案技术表见下。表2-1泰和县35kV万合

36、、地貌和地质条件本工程沿线地质情况较为简单，沿线无滑坡、泥石流等对线路路径构成威胁的不良地质。沿线地貌为平地及丘陵，海拔高程约50m100m。线路路径所经山坡自然稳定，地表一般生长有灌木和蕨类。沿线覆土呈硬塑至可塑状。根据1:4000000中国地震动参数区划图(GB18306-2009)，线路沿线地震动峰值加速度为0.05g，对应地震基本烈度为6度。2)矿产资源分布与开采根据到当地政府规划部门及矿产部门了解和实地调查的情况，线路经过地区无矿产资源。3)森林与植被沿线植被生长较好，主要覆盖有灌木和蕨类。在本次勘探揭露深度范围内，场地上覆土层为第四系上更新统残积层（Q3el），基岩为白垩系南雄组陆
37、相碎屑沉积岩（K2）。4）岩层特性及说明 按岩土层的成因类型、岩性结构、工程地质特征等，自上而下可依次划分为：粉质粘土（Q3el）、圆砾（Q3el）、强风化粉砂岩（K2）及中风化粉砂岩（K2）四个工程地质层。以下分别对各岩土层特性予以阐述：1、第四系上更新统残积层（Q3el）粉质粘土：黄褐、灰白色，稍湿，可塑、局部偏硬塑，切面稍有光泽，手捏有砂感，无摇振反应，干强度中等，韧性中等，组份以粉粒和粘粒为主，局部含铁锰质结核。该层全场地均有分布；该层层顶埋深0.000.00m，层底标高-3.20-2.90m，层厚2.903.20m，平均厚度3.06m。圆砾：浅黄、褐黄色，中密，饱和，主要成分石英、长
38、石，粒径2-20mm的颗粒含量超过总质量的50-60%，磨圆度好，呈亚圆状，级配良好，泥砂质充填。该层全场地均有分布；该层层顶埋深2.903.20m，层底标高-7.30-6.90m，层厚3.904.30m，平均厚度4.04m。2、白垩系南雄组陆相碎屑沉积岩（K2）据其岩性特征和风化程度，本次主要揭露为强风化岩、中风化岩及顶部薄层全风化岩。基岩岩性混杂，软硬不均，大体上以粉砂岩为主，夹杂较硬泥质粉砂岩及较软粗砂岩，总体强度低，浸水易崩解，风化迅速。强风化粉砂岩：全场地分布。紫红、棕红色。粉砂质结构，薄至中厚层状构造，岩芯呈饼状至短柱状，手易掰下碎块，局部顶部夹有薄层全风化岩，岩芯呈砂土状、碎屑状
39、；岩体较破碎，基本质量等级为V级，为极软岩。该层全场地均有分布；该层层顶埋深6.907.30m，层底标高-8.60-8.20m，层厚1.201.50m，平均厚度1.36m。中风化粉砂岩：全场地分布。紫红、棕红色。近水平层理发育，薄至中厚层状构造，岩芯短柱状至中、长柱状，手可折断岩芯，锤击声哑，较易断裂，裂隙发育一般，裂面较平直，裂面及层理面多见有Fe、Mn浸染。岩体较完整，基本质量等级为V级，为极软岩。该层全场地均有分布；且未揭穿，该层揭露层顶埋深8.208.60m，层底标高-12.40-11.30m，层厚3.103.90m，平均厚度3.50m。5） 地下水及水、土腐蚀性评价 1、地下水埋藏条
40、件根据地下水的埋藏条件、赋存条件，将地下水类型分为三种类型：（1）上层滞水：赋存于素填土中，主要受大气降水补给，弱透水性，赋水性较差。水位受季节影响明显，富水性差，水量较小。（2）第四系松散岩类孔隙水：主要赋存于圆砾层中，主要受大气降水及地表水补给。水位随季节变化，与地表水互为补给，枯水及平水期地下水向周边河道径流排泄，水位下降，丰水期地下水位上升。勘察期间地下水水位埋深1.62.7m，地下水位随季节性变化，年变幅可达23m。（3）基岩裂隙水，赋存于基岩裂隙中，沿裂隙渗流运移，以泉水形式向河水及低洼地带排泄，其补给主要为基岩侧向补给和第四系松散岩类孔隙水的垂直入渗补给，但其水量的大小与岩石破碎
41、程度、裂隙大小和连通程度有关；基岩为粉砂岩，细粒结构，强风化带的风化裂隙发育，勘察期间发现本场地基岩中存在一定水量。2、地下水腐蚀性评价勘察中采取了1组地下水样进行室内水质简分析，根据水质分析报告，据岩土工程勘察规范（GB50021-2001）（2009版）规范相关条文判定，按类环境、A类水考虑，场地地下水对混凝土结构具弱腐蚀性，对钢筋混凝土结构中的钢筋微腐蚀性。6）场地及地基地震效应根据江西省地震动参数区划工作用图江西省建设厅、江西省地震局（2003年），评估区地震动峰值加速度小于0.05g，地震基本烈度小于度，可不考虑砂土液化对工程的影响。7）岩土工程分析与评价1、场地稳定性及适应性评价根
42、据区域地层资料及现场调查访问，未发现对工程不利的河道、沟滨、墓穴、防空洞、孤石等埋藏物；同时场地也未见大的断裂构造通过，及坍塌，滑坡，沉陷，泥石流等不良地质作用，场地稳定性较好，为可进行建设的一般性场地，适宜拟建工程的建设。2、场地地基岩土分析与评价粉质粘土(Q3el)：呈可塑状，下部为承载力较高的圆砾层。中高压缩性，该层承载力从上至下逐渐变大，适宜做较轻建筑物持力层,但需进入持力层1.0m（表层含约0.3m耕植土）以上，基础类型可用浅基础。圆砾（Q3el):承载力较高，分布较均匀，层厚一般较大，下覆为基岩，其承载力高，可选作拟建建筑物基础持力层。第3章 线路沿线气象条件3.1 气象资料根据6
