A |     　　大连8月25日电 (记者 杨毅)全长11.6公里的海上超长钢栈桥25日在辽宁大连实现全线贯通，该栈桥为目前国内在建里程最长的海上钢栈桥。    Karachi, Oct 11 (UNI) Nobel laureate Malala Yousufzai arrived in Karachi on Tuesday to visit the flood-stricken areas of Pakistan, media reports said.

Yousufzai is being accompanied by her parents during the trip amid strict security.

Nobel laureate and girls' education campaigner is visiting the flood-affected areas to raise international awareness regarding the devastation caused by climate change in the South Asian nation.

Pakistan witnessed more than usual monsoon showers this season that sparked countrywide flooding and left a third of the nation underwater, causing damage to standing crops and roads and rail tracks in Sindh and Balochistan.

Yousufzai is expected to extend assistance from the Malala Fund for flood relief, according to Geo news reports.

In the first week of September, the Malala Fund issued an emergency relief grant to the International Rescue Committee (IRC).

The IRC will use the funds to provide psychosocial support to girls and women in flood-hit Sindh and Balochistan.

The funding will also be used to deliver emergency education services to ensure girls continue their education.

The assistance from the Malala Fund will help repair and rehabilitate ten damaged government schools for girls.

This is the second time that the 2014 Nobel peace prize winner has visited Pakistan.

In 2014, Yousafzai became the youngest recipient of the Nobel Peace Prize at the age of 17 in recognition of her efforts for children's rights.

B | 大连市长海(跨海)大桥项目(以下简称“长海大桥”)全长25.5公里，项目起点位于长海县大长山岛，横穿里长山海峡，于普兰店区皮口港东侧登陆。项目建成后，将终结长海县“朝发夕至、看天出岛”的交通困局。　　据介绍，长海大桥项目施工海域作业条件严苛，黄海海域风浪、潮汐变化频繁，施工干扰因素多，加之项目浅滩水域水深不足，常规施工船舶无法进场作业，存在施工效率低、安全风险高等问题，长期制约项目推进。　　为解决上述问题，项目团队决定建设钢栈桥为其核心配套施工设施。作为项目海上核心物料运输通道，钢栈桥承担建材转运、大型机械进场、人员通勤等重要职能，是名副其实的“海上施工生命线”。　　据中建股份长海大桥三标段项目经理倪家明介绍，钢栈桥项目建设规模体量突出，累计完成沉桩3431根，总用钢量6.7万吨。
